Lambda did not stabilize error in Lambda deployment

Question

We are getting the following error in deploying lambda through cloud formation. It was working fine for many months. We did not change our cloudformation template recently.

Resource handler returned message: "Resource of type 'AWS::Lambda::Version' with identifier 'arn:aws:lambda:ap-south-1:{ACCOUNT_ID}:function:ProfileServiceDevWavedevProfileServiceLambdaFunction:471' did not stabilize. Status Reason is An error occurred during function initialization." (RequestToken: , HandlerErrorCode: NotStabilized)

Answer

Hello!

Given the Status Reason, the function's version deployment failed because of an error encountered while executing the Lambda function initialization code (outside of handler).

Manually test the version, and check the Lambda execution logs for any issues during `INIT` phase
