Unable to upload app after recent SDK update

[Ian Rose]

I recently updated our Go SDK from 1.9.31 to 1.9.35 and now I am getting the following error whenever our deployer (which is a GCE instance) tries to deploy a new version of our App Engine app.  Here is some output:

$ appcfg.py --authenticate_service_account -A mn-load update test/
07:10 PM Application: mn-load (was: None); version: 1
07:10 PM Host: appengine.google.com
07:10 PM Starting update of app: mn-load, version: 1
07:10 PM Getting current resource limits.
2016-04-06 19:10:47,562 ERROR appcfg.py:2396 An error occurred processing file '': HTTP Error 401: Invalid response 403. Too many auth attempts.. Aborting.
Error 401: --- begin server output ---


--- end server output ---

Note that if I remove the " --authenticate_service_account" flag it kicks me over to a google login page so I suspect that the error is somewhere involved in obtaining an oauth token from the service account.

thanks,

DId you find a solution for the problem? I have the same issue when using --authenticate_service_account. With 1.9.36 and 1.9.37 I get the following error:

Ugh.  I just upgraded to 1.9.37 to work around this issue, and now I am getting the same error as you...

FYI it appears in my testing that changing

return oauth2client_gce.AppAssertionCredentials()

on line 3278 of appcfg.py to 

return oauth2client_gce.AppAssertionCredentials(['https://www.googleapis.com/auth/cloud-platform'])

will make things work again.
