Synthesis failed for python-appengine-admin

Hello! Autosynth couldn't regenerate python-appengine-admin. :broken_heart:
Please investigate and fix this issue within 5 business days.  While it remains broken,
this library cannot be updated with changes to the python-appengine-admin API, and the library grows
stale.
See https://github.com/googleapis/synthtool/blob/master/autosynth/TroubleShooting.md
for trouble shooting tips.

this library cannot be updated with changes to the python-appengine-admin API, and the library grows

Autosynth is still having trouble generating python-appengine-admin. :sob:
Please investigate and fix this issue within 5 business days.  While it remains broken,
this library cannot be updated with changes to the python-appengine-admin API, and the library grows
stale.
See https://github.com/googleapis/synthtool/blob/master/autosynth/TroubleShooting.md
for trouble shooting tips.

Autosynth is still having trouble generating python-appengine-admin. :sob:
Please investigate and fix this issue within 5 business days.  While it remains broken,
this library cannot be updated with changes to the python-appengine-admin API, and the library grows
stale.
See https://github.com/googleapis/synthtool/blob/master/autosynth/TroubleShooting.md
for trouble shooting tips.
Here's the output from running synth.py:
