I'm currently attempting to create a mock integration using the python AWS CDK for the purpose of running integration tests in an app.
This app needs to query an external API to validate a payload. The endpoint expects a Content-Type application/vnd.nasa.cmr.umm+json;version=1.6.3. For now, I would like the MockIntegration to always return a 200 status code with an empty response.
This is what I tried:
from aws_cdk import aws_apigateway
cmr_api = aws_apigateway.RestApi(
self, f"integration-test-cmr-api-try",
)
aws_apigateway.Resource(
self, "mock-cmr-validation", parent=cmr_api.root, path_part="ingest"
).add_resource(
"validate"
).add_method(
http_method="POST",
integration=aws_apigateway.MockIntegration(
request_templates={
"application/vnd.nasa.cmr.umm+json;version=1.6.3": json.dumps({"statusCode": 200})},
integration_responses=[
{
"statusCode": "200",
"responseTemplates": {"application/json": json.dumps({})},
}
],
),
method_responses=[
{
"statusCode": "200",
"responseModels": {
"application/json": aws_apigateway.Model.EMPTY_MODEL
},
}
],
)
Unfortunately a request to the generated gateway returns:
curl --request POST 'https://trfjg7ckha.execute-api.us-east-1.amazonaws.com/prod/ingest/validate' \
--header 'Content-Type: application/vnd.nasa.cmr.umm+json;version=1.6.3' \
--data-raw '{}'
Status code 500, {"message": "Internal server error"}.
Setting only application/json (or even application/vnd.nasa.cmr.umm+json) as the key in MockIntegration.request_templates, and using that as the Content-Type in the request, returns the intended result (status code 200, empty response). This makes me wonder if the issue can potentially be in setting the ;version=1.6.3 with the Content-Type?
Any help would be greatly appreciated!
