Error when integrating API Gateway with Aws Lambda



I'm getting an error when integrating API Gateway with Aws Lambda, I make an Http REST POST call and I get the following JSON: Enter image description here

I debugged via CloudWatch but I can't find any reference to the reason for the error, my lamdba script receives a call from the gateway and makes a call to an external backend via HTTP REST POST. I haven't found the cause of this behavior yet.

Please check the following steps as mention in below

Step 1: Verify that the input format expected by the Lambda function matches the format of the data sent in the POST request. Step2: Check the configuration of AWS API Gateway in the request and request mapping are configured correctly or not . Step 3: Check the payload of the POST request. A common cause for a 409 error is sending data that conflicts with the current state of the resource
