Passing url query parameters in http liveness and readiness probe in kubernetes - kubernetes

Question

I am trying to configure the HTTP liveness probe as follows:
livenessProbe:
httpGet:
path: /rest/sends/get?source=mwTESt2VP3Q9M99GNWYvvaLQ1owrGTTjTb #sends API to test address
port: 4000
httpHeaders:
- name: Authorization
value: Basic cnBjOnUzSGRlM0xvaWI1SGpEcTFTZGVoQktpU1NBbHE=
initialDelaySeconds: 60 #wait this period after staring fist time
periodSeconds: 30 # polling interval
timeoutSeconds: 30 # wish to receive response within this time period
Here, the URL path contains query parameters along with an authentication header (base64 encoding of username:password)
However, I get the following error:
ERROR in app: Exception on /rest/sends/get [GET] (http 500)
I checked that this indeed works with status code 200 after logging into the pod
curl http://username:password#localhost:4000/rest/sends/get?source=mwTESt2VP3Q9M99GNWYvvaLQ1owrGTTjTb
This question is probably similar to this one Kubernetes liveness probes with query string parameters
But, according to it, this should have already been fixed. I am using Kubernetes on Google cloud version: 1.10.7-gke.2 on both master and other nodes.
Am I missing something?
EDIT
In the server access log, I get the following error
10.0.2.1 - - [10/Oct/2018 03:50:45] "GET /rest/sends/get?source=mwTESt2VP3Q9M99GNWYvvaLQ1owrGTTjTb HTTP/1.1" 500 -

The server is actually a counterparty-server https://github.com/CounterpartyXCP/counterparty-lib
I am not really sure what the problem is.

Answer 1

I added this header to the request
httpHeaders:
- name: Authorization
value: Basic cnBjOnUzSGRlM0xvaWI1SGpEcTFTZGVoQktpU1NBbHE=
- name: Accept
value: application/json
And now it's working alright.

Answer 2

As you can see, the server logs at the end line, in the function getitem that return "unicodify_header_value" the Class HttpHeaders.Names 'HTTP_ACCEPT' wasn't found, this what was missing in your "httpHeaders" config.
nice catch.
