I’ll introduce how to fix the Task timed out after 6.00 seconds error when a function deployed to AWS Lambda with Serverless Framework encounters this issue.

(Prerequisite) AWS Lambda default timeout is 6 seconds

According to the official documentation and forums, the default timeout for AWS Lambda appears to be 6 seconds.

• Serverless Framework - AWS Lambda Guide - Serverless.yml Reference
• Task timed out after 6.00 seconds - Serverless Framework - Serverless Forums

# serverless.yml
provider:
  timeout: 10 # The default is 6 seconds. Note: API Gateway current maximum is 30 seconds

functions:
  usersCreate: # A Function
    timeout: 10 # Timeout for this specific function.  Overrides the default set above.

How to fix Task timed out after 6.00 seconds

Since The default is 6 seconds., I resolved this by extending the timeout setting for the function that timed out to 60 seconds.

That’s all from the Gemba where I resolved the Task timed out after 6.00 seconds error.
