Api Gateway with Lambda Integration Failure

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.

Is this what you're referring to or something different?

I have enabled execution logs on Rest API gateway. While I send 500 requests through locust for same endpoint, more than 60 % comes HTTP 500 error and remaining only success. Here is the error log IP ADDRESS- - [05/Jan/2022:02:05:59 +0000] "POST /{proxy+} HTTP/1.1" 500 ID-Internal server errorINTEGRATION_FAILURE

I have followed the link you shared and above error comes.

This problem is solved by increasing quota for concurrency.
