AppEngine: No Module Named Pyasn1.compat.binary

I keep getting the following error when hitting my AppEngine server: ERROR 2017-09-20 07:16:06,978 wsgi.py:263] Traceback (most recent call last): File '/usr/lib/google-cloud

Solution 1:

Lots of thanks to Dan Cornilescu! It turns out that my app.yaml config was the culprit, specifically the skip_files directive.

The bad config looked like:

skip_files:
- ^(.git/.*)
- ^.*bin(/.*)?
- ^.*node_modules(/.*)?
- ^.*public(/.*)?
- ^.*src(/.*)?
- ^env$
- ^(.*/)?.*\.pyc$

The updated config looks like:

# Skip any non-essential files for uploading during deploys.
skip_files:
# Defaults, see: https://cloud.google.com/appengine/docs/standard/python/config/appref#skip_files/
- ^(.*/)?#.*#$
- ^(.*/)?.*~$
- ^(.*/)?.*\.py[co]$
- ^(.*/)?.*/RCS/.*$
- ^(.*/)?\..*$
# Custom
- ^(.*/)?.*/bin/.*$
- ^(.*/)?.*/env/.*$
- ^(.*/)?.*/none_modules/.*$
- ^(.*/)?.*/public/.*$
- ^(.*/)?.*/src/.*$

So a combo of bad regex and skipping the wrong files broke the local app server, and fixing it got it up and running again.
