Looks like it intermittently fails. Not sure why though. 

It says credentials are wrong. Puppet doesn't seem to be failing...

https://ci.chromium.org/buildbot/chromium.webkit/WebKit%20Android%20%28Nexus4%29/75804 is an example. The log says


Your "Oauth 2.0 User Account" credentials are invalid. For more help, see "gsutil help creds", or re-run the gsutil config command (see "gsutil help config").

I think it's uploading a logcat. Any ideas?

Note: "gsutil.py --force-version 4.7" - I think I've seen some complains about 4.7 earlier. This version is *really* old. I believe we no longer have reasons to enforce this old version, and it might be causing incompatibilities with GS API.

On my laptop:

$ gsutil --version
gsutil version: 4.29

Issue 826036 has been merged into this issue.

This upload step sometimes passes, sometimes fails with this error.  Could there be a bug in 4.7 causing this flakiness?  Is there any harm to use the latest version?

Issue 827255 has been merged into this issue.

This seems to be becoming more widespread, the same error message appears now on all of:

Raising Pri.

gsutil versions before 4.20 gets this error
