Receiving an "function not found" error while trying to deploy a node-aws example

[examples/aws-node-upload-to-s3-and-postprocess at master · serverless/examples · GitHub]

Error:

An error occurred while provisioning your stack: PostprocessLambdaFunction
- Function not found: arn:aws:lambda:us-east-1:346388367522:function:s3-upload-and-process-dev-postprocess.

The first time I pulled and deployed this example, I did not get this error.

I am new to serverless, but got another example running. What is the best way to try to debug errors like this with serverless and AWS?

Looks a simple typo somewhere caused the issue. I re-recreated from scratch and no longer have the issue.
