Api Gateway with Lambda Integration Failure

0

Most of time the request becomes success where my backend is deployed in Lambda and request is made through client to API gateway to Lambda. Randomly, Api gateway shows HTTPError **500 Internal server error INTEGRATION_FAILURE. **I looked cloudwatch and X ray but couldnot figure out what is causing this. Out of 1000 requests, sometimes 400 requests are success with 200 and remaining requests with Internal server error.

I would recommend enabling execution logs on API Gateway and check the logs there for any failures. I would guess that it has something to do with the format of the response being sent from the Lambda function.

This problem is solved by increasing quota for concurrency.
