'Amazon Websocket API Gateway fails to connect with error Unexpected server response: 500
I have a Websocket API Gateway with a HTTP backend (via vpclink and no proxying) with three routes: default, connect and disconnect.
When I try to connect using wscat it fails with: Unexpected server response: 500
The backend service returns 200 so it is the gateway that returns 500.
Looking in CloudWatch I see the following error message:
Execution failed due to configuration error: No match for output mapping and no default output mapping configured. Endpoint Response Status Code: 200
What is the reason for this error? Does this mean I have to add an integration response? I thought this was optional.
