ExecutionFailed for Lambda.ResourceNotFoundException

[王婷]

Thanks a lot for the repo!
I tried to create a sample according to the README said.
But got the error in the following. Did I set the wrong parameters?

offline: Attempt to invoke function 'hello' failed. Function does not exists.

Set the ARN to arn:aws:lambda:us-east-1:123456789012:function:project-name-dev-hello and got the right result.
I am fine.
Thank you!
