I'm implementing Amplify Flutter and want to connect it to our own custom GraphQL endpoint (i.e. non-AppSync). I am however having trouble getting it to work. The official documentation is not super-clear on this (at least not for those of us who are completely new to Amplify). What I have done:
In pubspec.yaml, I’ve added and installed the amplify_api package.
In main.dart, I’ve updated _configureAmplify() to add the AmplifyAPI() plugin.
In amplifyconfiguration.dart, I have manually added the following snippet:
"api": {
"plugins": {
"awsAPIPlugin": {
"xxxxxAPI": {
"endpointType": "GraphQL",
"endpoint": "http://xxxxxxxx.eba-fmuh2afu.eu-north-1.elasticbeanstalk.com/query",
"region": "[REGION]",
"authorizationType": "AMAZON_COGNITO_USER_POOLS"
}
}
}
}
But I keep getting the error "There is no API configured for this plugin with matching endpoint type." What am I doing wrong? (Note: I presume that I don't have to add any "region" value if I'm pointing to our own custom GraphQL endpoint).
I was able to fix this issue by closing the app and uninstalling it, then run again and log in to start fetching API

I have incorporated the solutionConfig as part of HPO in AWS personlaize service.
solutionConfig = {
"optimizationObjective": {
"itemAttribute": "ITEM_WEIGHT",
"objectiveSensitivity": "HIGH"
},
I am getting the following error
Unknown parameter in solutionConfig: "optimizationObjective", must be one of: eventValueThreshold, hpoConfig, algorithmHyperParameters, featureTransformationParameters, autoMLConfig]
It looks like you may be using a version of the AWS SDK that does not include support for the optimizationObjective parameter of the solution config. Check to make sure that you're using the latest version of the AWS SDK.
I integrated vue store front with magento 2, frontend works fine but product images not display in frontend. It throws error Unable to compile TypeScript:\nsrc/image/action/local/index.ts(27,18): error TS2339: Property 'query' does not exist on type 'Request<any, any, any, any>'. imagemagick is also installed and imgurl in local.json is also defined.
Anyone please know about this why error display.
It is about this.req which is typeof Request from express - it has query property. Please make sure you have yarn.lock from the original repo and reinstall dependencies.
If you are using docker, you might need to add:
- './yarn.lock/var/www/yarn.lock'
To volumes section in the docker-compose.nodejs.yml
i have found a simple solution you can try that
copy all your magento 2 pub/media data in vue-storefront-api/var/magento-folder/pub/media
Or
create a symlink if you are working on localhost
vue-storefront-api/config/local.json
"magento2": {
"imgUrl": "http://magento-domain/pub/media/catalog/product",
"assetPath": "/../var/magento-folder/pub/media",
}
vue-storefront/config/local.json
"images": {
"useExactUrlsNoProxy": false,
"baseUrl": "http://localhost:8080/img/",
"useSpecificImagePaths": false,
"paths": {
"product": "/catalog/product"
},
"productPlaceholder": "/assets/placeholder.jpg"
},
run command in vue-storefront and vue-storefront-api
I'm using the docker image of Keycloak 10.0.2. I want Keycloak to supply access_tokens that can be used by Hasura. Hasura requires custom claims like this:
{
"sub": "1234567890",
"name": "John Doe",
"admin": true,
"iat": 1516239022,
"https://hasura.io/jwt/claims": {
"x-hasura-allowed-roles": ["editor","user", "mod"],
"x-hasura-default-role": "user",
"x-hasura-user-id": "1234567890",
"x-hasura-org-id": "123",
"x-hasura-custom": "custom-value"
}
}
Following the documentation, and using a script I found online, (See this gist) I created a Script Mapper jar with this script (copied verbatim from the gist), in hasura-mapper.js:
var roles = [];
for each (var role in user.getRoleMappings()) roles.push(role.getName());
token.setOtherClaims("https://hasura.io/jwt/claims", {
"x-hasura-user-id": user.getId(),
"x-hasura-allowed-roles": Java.to(roles, "java.lang.String[]"),
"x-hasura-default-role": "user",
});
and the following keycloak-scripts.json in META-INF/:
{
"mappers": [
{
"name": "Hasura",
"fileName": "hasura-mapper.js",
"description": "Create Hasura Namespaces and roles"
}
]
}
Keycloak debug log indicates it found the jar, and successfully deployed it.
But what's the next step? I can't find the deployed mapper anywhere in the GUI, so how do I activate it? I tried creating a protocol Mapper, but the option 'Script Mapper' is not available. And Scopes -> Evaluate generates a standard access token.
How do I activate my deployed protocol mapper?
Of course after you put up a question on SO you still keep searching, and I finally found the answer in this JIRA issue. The scripts feature has been a preview feature since (I think) version 8.
So when starting Keycloak you need to provide:
-Dkeycloak.profile.feature.scripts=enabled
and after that your Script Mapper will show up in the Mapper Type dropdown on the Create Mapper screen, and everything works.
I am trying to integrate Azure App insights service into the service fabric app for logging and instrumentation. I am running fabric code on my local VM. I exactly followed the document here [scenario 2]. Other resources on learn.microsoft.com also seem to indicate the same steps. [ex: https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-diagnostics-event-aggregation-eventflow
For some reason, I don’t see any event entries in App insights. No errors in code when I do this:
ServiceEventSource.Current.ProcessedCountMetric("synced",sw.ElapsedMilliseconds, crc.DataTable.Rows.Count);
eventflowconfig.json contents
{
"inputs": [
{
"type": "EventSource",

]
}
],

{
"type": "drop",

}
]
}
],

}
In ServiceEventSource.cs
[Event(ProcessedCountMetricEventId, Level = EventLevel.Informational)]
public void ProcessedCountMetric(string operation, long elapsedMilliSeconds, int recordCount)
{
if (IsEnabled())
WriteEvent(ProcessedCountMetricEventId, operation, elapsedMilliSeconds, recordCount);
}
EDIT
Adding diagnostics pipeline code from "Program.cs in fabric stateful service
using (var diagnosticsPipeline =
ServiceFabricDiagnosticPipelineFactory.CreatePipeline($"{ServiceFabricGlobalConstants.AppName}-mystatefulservice-DiagnosticsPipeline")
)
{
ServiceRuntime.RegisterServiceAsync("mystatefulserviceType",
context => new mystatefulservice(context)).GetAwaiter().GetResult();
ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id,
typeof(mystatefulservice).Name);
// Prevents this host process from terminating so services keep running.
Thread.Sleep(Timeout.Infinite);
}
Event Source is a tricky technology, I have been working with it for a while and always have problems. The configuration looks good, It is very hard to investigate without access to the environments, so I will make my suggestions.
There are a few catches you must be aware of:
If you are listening etw events from a different process, your process must be running with a user with permissions on 'Performance Log Users. Check which identity your service is running on and if it is part of performance log users, who has permissions to create event sessions to listen for these events.
Ensure the events are being emitted correctly and you can listen to them from Diagnostics Events Window, if it is not showing there, there is a problem in the provider.
For testing purposes, comment out the line if (IsEnabled()). it is an internal check to validate if your events should be emitted. I had situations where it is always false and skip the emit of events, probably it cache the results for a while, the docs are not clear how it should work.
Whenever possible, use the EventSource from the nuget package instead of the framework one, the framework version is full of bugs and lack fixes found in the nuget version.
Application Insights are not RealTime, sometimes it might take a few minutes to process your events, I would recommend to output the events to a console or file and check if it is listening correctly, afterwards, enable the AppInsights.
The link you provide is quite outdated and there's actually a much better way to log application error and exception info to Application insights. For example, the above won't help with tracking the call hierarchy of an incoming request between multiple services.
Have a look at the Microsoft App Insights Service Fabric nuget packages. It works great for:
Sending error and exception info
Populating the application map with all your services and their dependencies (including database)
Reporting on app performance metrics,
Tracing service call dependencies end-to-end,
Integrating with native as well as non-native SF applications
I have two applications:
hrportalcore: The core application with BaseController, ...
hrportalrequestleave: A sample application extended from the hrportalcore application
The hrportalcore has the namespace de.example.core and there are the dataSources also maintained. (sap.app.dataSources in manifest.json). The datasource is:
[...]
"HRPOJavaLeave": {
"uri": "<path>",
"type": "OData",
"settings": {
"annotations": [],
"odataVersion": "2.0",
"localUri": ""
}
}
[...]
The datasources can be used without any problems in the extended application but the console brings the following errors:
It says the datasource contains errors, but it can be used (strange?).
Another thing is, that the Component-preload.js file is loaded from a wrong place once a time. The application works without problems, but it is - as said - loaded once from a wrong location?
My manifest.json of the hrportalrequestleave looks like in the extension part (sap.ui5.extends):
[...]
"extends": {
"component": "de.example.core",
"extensions": {}
},
[...]
The parent is defined rightly in the neo-app.json as /parent to show to hrportalcore.
jQuery.sap.declare("de.example.request.leave.Component");
// use the load function for getting the optimized preload file if present
if (!jQuery.sap.isDeclared("de.example.core.Component")) {
sap.ui.component.load({
name: "de.example.core",
// Use the below URL to run the extended application when SAP-delivered application is deployed on cloud
url: jQuery.sap.getModulePath("de.example.request.leave") + "/parent"
// we use a URL relative to our own component
// extension application is deployed with customer namespace
});
}
this.de.example.core.Component.extend("de.example.request.leave.Component", {
metadata: {
manifest: "json"
}
});
This all happens in the Fiori Launchpad of HANA Cloud Platform
Solution
manifest.json of hrportalcore: Always use the up-to-date version which you have deployed on your HCP in the applicationVersion property:
{
"_version": "1.2.0",
"sap.app": {
"_version": "1.2.0",
"applicationVersion": {
"version": "1.6.2"
},
...
manifest.json of hrportalrequestleave (Extension project): As above, always use the up-to-date version which you have deployed on your HCP in the applicationVersion property.
DataSource not found?!
If you have a extension project (like hrportalrequestleave < hrportalcore), then the manifest.json of both applications are merged like jQuery.extend(...). All properties, expect the sap.app tree, because it describes really the application and can not be copied from parent extension.
Now, when you use a dataSource from the parent extension, it will not be found. That means for you, you must define the sap.app.dataSources in the extension project manifest.json.
The error in the log
"Error in application dependency de.example.core.Component: No descriptor was found"
suggests that the manifest.json contains a dependency to "de.example.core.Component" instead of "de.example.core". According to your code snippets, the "extends" dependency is correct. Do you have other dependencies?
The AppIndex in the backend calculates the transitive closure of dependencies and if it can't find an installation with that ID, the above error is created and logged on the client side.
If your manifest.json looks okay but might have contained a wrong dependency in the past, then it might be necessary to re-run the AppIndex (or schedule it for a regular run).
The fact that the app works despite the config error is caused by the code that you've shown above. It explicitly loads the de.example.core component from an explicitly calculated URL. But before that step, the framework already tries to load it, based on the information in the manifest.json and there the information about the explicit URL is missing.
BTW: the code that calculates the URL suggests that even after fixing the manifest.json, the AppIndex might not find the component as it seems to be stored in a sub package of the de.example.request.leave app. Not sure if the AppIndex can handle this (it can handle nested components if they are listed as embedded components in the top level manifest.json, but I'm not sure if it recognizes such embedded components in the dependencies section. As a result it might try to load the embedded component although it has been loaded together with the enclosing component already.
