ps we once had a test account and maybe I accidentally stopped it from running when updating CI config and/or removing travis.. I opened #218 to get automated integration test with a real account working again, which would have prevented not noticing this. I ad-hoc tested the server once in the last couple months, but broke it after!

I found when the docker CI workflow was accidentally deleted.. several years ago. running the tests again in case the credentials still work.

ok rolling back CI as the google-cloud account was revoked, which is not terribly surprising the years

we'll just do ad-hoc integration tests until someone at google gives us an account again.

thanks for the look @reta!

I just tested the 2.2.2 tag, and it works like a charm. Thank you for the fix!
