Appengine remote_api_shell not working with application-default credentials since update

问题

I recently updated my gcloud libraries from 118.0.0 to 132.0.0 and immediately remote_api_shell no longer worked. I went through a number of permutations of re-logging in, to set the application-default credentials through gcloud, and to use a service account and environment variable. All permutations failed with the same error message:

    Traceback (most recent call last):

After back revving through 131.0.0 and 130.0.0, I just went back to 118.0.0, re-logged in and everything worked fine.

I did not update the running application after updating gcloud, as I'm in the middle of a release cycle at the moment, so that may have been the issue, but any help would be appreciated. Thanks!

TL;DR: This was fixed in gcloud version 134

Original answer: Run

gcloud auth application-default login --scopes=https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/userinfo.email

Now your remote shell should work again.

Details: I think this was broken by the 128.0.0 update, along with the changes to the gcloud auth login command. The old tokens have the following scopes (according to Google's tokeninfo endpoint):

https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/cloud-platform https://www.googleapis.com/auth/appengine.admin https://www.googleapis.com/auth/compute https://www.googleapis.com/auth/plus.me

The new tokens from gcloud auth application-default login without any options only have:

https://www.googleapis.com/auth/cloud-platform

This is documented in gcloud auth application-default login --help

Version 134 details: The scopes requested are now:

https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/cloud-platform
