Description
Is there an existing issue for this?
- I have searched the existing issues
Current Behavior
When performing any requests with path parameters with validation enabled the following error message is returned
GET http://localhost:4566/restapis/<apigw_id>/local/_user_request_/test/world
returns
{"Type": "User", "message": "Invalid request body", "__type": "InvalidRequest"}
Expected Behavior
Path parameter validation works like AWS, i.e. validation is performed, lambda is invoked and response returned to caller.
GET http://localhost:4566/restapis/<apigw_id>/local/_user_request_/test/world
returns
"hello world"
How are you starting LocalStack?
With the localstack script
Steps To Reproduce
How are you starting localstack (e.g., bin/localstack command, arguments, or docker-compose.yml)
localstack start
Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)
See project in zip archive - localstack-path-parameter-test.zip. Also included below.
To deploy to localstack:
yarn installnpx sls deploy --stage local --region eu-west-2
This has two endpoints. The first, test, works but the second endpoint, broken-test, fails with the error Invalid request body.
It looks like the error is caused by localstack not being able to handle AWS::ApiGateway::RequestValidator correctly.
Also if you try to fix an endpoint by removing the validation, i.e. change the broken-test endpoint to:
broken-test:
handler: handler.test
events:
- http:
path: broken-test/{value}
method: get
Then after deploying and hitting this endpoint you get an error like
{
"__type": "InternalError",
"message": "exception while calling apigateway with unknown operation: An error occurred (NotFoundException) when calling the GetRequestValidator operation: Validator 06ce6f for API Gateway 5ajrq316ln not found"
}
