This is clarification of the OP
I have a spring gateway that uses eureka server to route requests to registered spring boot eureka clients.
What I am seeing is that every request results in a 301 redirect containing a Location header. It seems that because the request is received on https://my-api.io/payment/payment-intent spring-gateway looks it up based upon these rules:
server.forward-headers-strategy=framework
feign.hystrix.enabled=false
spring.cloud.config.discovery.enabled = true
....
spring.cloud.gateway.routes[11].id=orders-service
spring.cloud.gateway.routes[11].uri=lb://orders-service
spring.cloud.gateway.routes[11].predicates[0]=Path=/payment/**,/order/**
spring.cloud.gateway.routes[11].predicates[1]=Method=GET, POST
spring.cloud.gateway.routes[11].predicates[2]=Header=APIKEY, (.*)
spring.cloud.gateway.routes[11].filters[0]=AuthorizationHeaderFilter
## these next two apparently have no impact
spring.cloud.gateway.routes[11].filters[1]=RewritePath=/(?<segment>.*),/payment/$\{segment},/order/$\{segment}
spring.cloud.gateway.routes[11].filters[2]=RedirectTo=301, lb://orders-service
And then returns the Response Headers:
Server: awselb/2.0
Date: Tue, 24 Jan 2023 17:58:36 GMT
Content-Type: text/html
Content-Length: 134
Connection: keep-alive
Location: https://my-api.io:8081/payment/payment-intent
If I enable "follow redirects" in Postman or curl, then it works fine. But that won't work in a mobile app, so I really need to have spring-gateway just route the call on first pass. I don't know if this is because the routes.uri defines the as coming from the load-balancer (since ports are dynamic and there are likely multiple instances) url so it seems like a different url or what.
I am desperately trying to find a way so that the request is just processed and not bounced back with a 301.
Now that I have context around the issue it turns out the issue was not with Spring Gateway since its just a passthru (after some validation). Thanks to spencergibb I was able to rule out gateway and realize it was a forwarding issue in AWS.
My interface (an MKR Wifi 1010 Arduino) runs a very simple REST API, but when testing it with Mulesoft's Advanced Rest Client, I get this error:
The requested URL can't be reached
The service might be temporarily down or it may have moved permanently to a new web address.
The response status "0" is not allowed. See HTTP spec for more details: https://tools.ietf.org/html/rfc2616#section-6.1.1
When I check it with telnet though, it looks fine:
[bf#localhost ~]$ telnet 192.168.178.185 80
Trying 192.168.178.185...
Connected to 192.168.178.185.

HTTP/1.1 200 OK
Connection: close
Content-Length: 9
Content-Type: application/json
"Success"
Connection closed by foreign host.
My question now is, is the rest client broken, or am I missing something in my reply? Of course I want any REST client to be able to process my interface correctly.
I have an API Gateway integration for a method/resource which works when I call it from the API but not when I actually call it:
$ aws apigateway test-invoke-method --rest-api-id $REST_API_ID \
--resource-id $RESOURCE_ID --http-method GET | jq -r .log,.body
This works out fine and I get the following output:

However, I cannot access this at my URL, which is api.naftuli.wtf/v1/status.json. I have stages defined at glhf, stable, and v1, so by replacing that, you will see different responses. I just simply want a dummy response that returns a 200 JSON blob.
My Terraform for the resources is here as a Gist. Hopefully this fully shows my API Gateway configuration.
If I test invoke this from the CLI or from the web console, I get back what is expected. However, if I curl this from my deployed API at api.naftuli.wtf, I don't get anything nice:
$ for stage in glhf stable v1 ; do
> url="https://api.naftuli.wtf/${stage}/status.json"
> echo "${url}:"
> curl -i -H 'Content-Type: application/json' \
> https://api.naftuli.wtf/${stage}/status.json
> echo -e '\n
> done

My understanding of stages were that they were additional path prefixes to the base path under which all API resources were available. If I had a stage called v1 with a path of /v1, I'd expect that an API Gateway resource for status.json will be basically mapped under /v1, yielding /v1/status.json.
I may be misunderstanding how API Gateway base path mappings and stages work, but CloudWatch tells me that the call is at least happening, though failing for some obscure reason:

Apparently only traffic across the V1 stage is getting through to CloudWatch logs. I have a misconfiguration somewhere and I can't seem to find it.
Can you try and change you request template in the integration request setup to this:
{
"statusCode": 200
}
API Gateway looks for the status code to return in the response in your integration request template. The response is generated by the mapping template in the integration response. I can see from your terraform setup that you are loading the output json file in the integration request template. This is content API Gateway does not expect.
With Mock Integration Amazon API Gateway there are 2 common reasons for 500 Internal Server error.
Check the mapping template in Integration Request and ensure that you are passing statusCode as an integer to the MOCK Integration endpoint.
{
"statusCode": <Integer_Status_code>
}
Note: Make sure that status code is passed as integer not string.
Correct : 200 Incorrect : "200"
Mock Integrations do not support the binary content. If the API is enabled with bixnary support and has application/json or */* set as binaryMediaTypes, MOCK Integration endpoints would throw a 500 Internal server error when trying to transform the content.
A workaround is to update the contentHandling property of the MOCK Integration to CONVERT_TO_TEXT

For my case, when I deploy the lambda with serverless framework, the OPTIONS returns 200 when called. However, when I configure manually on AWS API Gateway, it returns 500 Internal Server Error.
When I check the execution log of API gateway, it said
(ee0a42d9-2cfc-4788-8679-00fbd7938cf1) Method request body before transformations: [Binary Data]
(ee0a42d9-2cfc-4788-8679-00fbd7938cf1) Execution failed due to configuration error: Unable to transform request
(ee0a42d9-2cfc-4788-8679-00fbd7938cf1) Gateway response body:
{
"message": "Internal server error"
}
After you create the Resources and OPTIONS methods, select the OPTIONS method then
At Method Execution --> Integration Request --> expand the Mapping Templates, choose "When no template matches the request Content-Type header". Add or select "application/json" in the Content-Type. Click the "application/json", and in the Generate template, paste
{statusCode: 200} without any double quote. Note, if the {"statusCode": 200} exists but with double quote, remove it to be the same as above. Then Save it
At Method Execution --> Integration Response --> expand the 200 response status --> Mapping Template --> Add or select "application/json" in the Content-Type. Make sure that the Generate template box is empty. Then Save it
At Method Execution --> Method Response --> expand the 200 response. In Response Headers for 200, add three headers: Access-Control-Allow-Headers, Access-Control-Allow-Methods, and Access-Control-Allow-Origin. Leave the Response Body for 200 to be empty
Action --> Enable CORS for the Resource
Action --> Deploy API
You have at least two distinct problems with your configuration.
First, one of your three base path mappings doesn't match the way you're trying to invoke your API. Note that the base paths don't have to be the same as your stage names, but they can be if you desire. Since your base path mappings include base paths and stage names, API Gateway is expecting the invoke path to include a base path mapping and not a stage, so it is interpreting the [glhf stable v1] portion of your path as a base path and looking for the corresponding base path mapping entry to determine the API and stage to use. This works fine for the v1 and glhf base paths which return 500 (indicating a different problem). The stable base path (in https://api.naftuli.wtf/stable/status.json) returns a 403 Forbidden because there is no base path of "stable" defined for the domain name api.naftuli.wtf. The stable stage is mapped to the "latest" base path, so calling https://api.naftuli.wtf/latest/status.json should be the way to call the stable stage. This doesn't currently work, and I don't know why. If you tell me what region your running this in, I can look-up the config and do more digging.
The second problem is indicated by the following entry from your CloudWatch logs:
Execution failed due to configuration error: statusCode should be an integer which defined in request template
Can you check that your integration request template (in the file your reference in "${file("${path.module}/files/status.json")}") contains "statusCode: 200" as a top level attribute.
I also found it surprising that you're using the same file for a request template and a response template.
Having had the identical errors I found what helped me solve this issue was to delete my OPTIONS request definition in the AWS Console. I then followed the console's "Enable CORS" form which created a new OPTIONS method.
I subsequently ran terraform plan and looked at the diff between my OPTIONS defintion and theirs. Given that the AWS Console created OPTIONS method worked I applied the changes.
Using terraform 0.12 or greater makes this possible as the terraform plan output detail is more fine grained.
I was doing this in CloudFormation.
It took me a while to get it and the accepted answer here was extremely helpful, but a little vague, so adding some more info.
Stefano Buliani's answer, in CloudFormation YAML, looks like:
RequestTemplates:
application/json: |
{ statusCode: 200 }
What was especially weird here was apparently, the fix was simply to create a deployment using the AWS CLI for each of the stages. Apparently, Terraform was not updating or re-kicking deployments on changes, and so my changes never got out.
I had a similar problem and eventually figured out that my client was using a different content type than I expected. I had foolishly assumed it would use application/json, but it was some custom json thing. In my setup, API Gateway is logging to cloudwatch, which is where I found the content type it received from the client. Once I updated the content type in the request template of the mock integration, things worked as expected.
I have HAproxy is behind an AWS ELB. As soon as i remove the ELB, i can get the custom error page. but, with ELB in the front of Haproxy, i get HTTP/1.1 504 GATEWAY_TIMEOUT Content-Length: 0 Connection: keep-alive.
Can anyone tell me what is going on please? Thanks
errorfile:

Me and a coworker just had the same problem. After receiving the timeouts, and reading amazon definition for this type of http code, i got in my head my error file was "malformed". After a lot of trys, we managed to discover that there is something funny with the CL-RF (new lines) on the error file "header".
I downloaded HaProxy default file from their git (https://raw.githubusercontent.com/haproxy/haproxy/60220bbc4b6b3c4279d3c96232cf2c2461ecc55e/examples/errorfiles/503.http) and when you open it on vi(m) it has a ^M (CR) sign on the headers(everything before the body, including the empty line separating them). If you cant download it, you could just write it (just the top part) on wordpad or something like it (dos) and then send it to you unix machine.
So i wrote my on file using their header and now everything works fine.
Cheers.
I'll start with the log that I am receiving below:
Dec.15.11.56-Rf: Incoming Request URL: /

Basically, when I go to mlocal.cldeals.com, it loads fine. If I click on another page, say mlocal.cldeals.com/products, that loads fine as well. The issue seems to be when I go to the account page and try to switch back to the homepage, maybe some type of security issue? When I try to switch back to mlocal.cldeals.com, the home page, it boots me off and sends me to www.cldeals.com. Is there something I can add to force this from not happening? Additionally, is this just a local server issue that would go away when I launch it on Moovweb's server? Any help is greatly appreciated.
Thank you.
It looks like the backend response to https://www.cldeals.com is a 302 to http://www.cldeals.com:80/. Not sure why that is the case (see note below *)
curl -v -o /dev/null https://www.cldeals.com
This response contains a hardcoded Location header and your project is passing along the response as is, which is why you are being booted off your local server.
Because the Location header value has a port specified, you'll need to modify your config.json to include this line in the mapping:
{
"host_map": [
"$.cldeals.com => www.cldeals.com",
"$.cldeals.com => www.cldeals.com:80"
]
}
This way, the SDK knows to rewrite that specific host:port value... (By default all HTTP requests go through port 80, so that information isn't really necessary)
*This is might be bug in the backend implementation because once you log in, you should be in HTTPS mode until you log out. (I can see some pages with personal information being transmitted over plain HTTP)
