an example can be executed without running the migration. I am guessing it required readme file update as the offline command is twice. if not then definitely a bug in the example. Hope this helps.

I also hit an error something related to this. As soon as I run Serverless offline start, I get some outputs pertaining to the start and then this exception:

The curl commands specified in README doesn't work either.
