What steps did you take and what happened:
I try to execute fairing on local repository but it failed.
Is there any comments?

What did you expect to happen:
example/simple/main.py works fine on local repository.

Anything else you would like to add:
I am looking into "docker logs registry" it returns 404 and 500 error.
500 says invalid character '\x1f' looking for beginning of value
