I have same error - increasing the timeout resolved it:

In the AWS Management Console:

lambda function -> configuration -> General configuration -> Edit Timeout

The default Lambda timeout is 3 seconds.

To resolve this do one of the following:

  • Increase the timeout of your Lambda function, it can be upto 15 minutes. The recommendation would be to set it to the duration of how long you anticipate it will take.
  • Increase the resources (memory/CPU) so that your function is quicker at performing its target action.
