'DEBIAN7' for property vm_image_type is not an allowed choice" error on deploy

[sam0x17]

I just suddenly got this error this morning when I tried to deploy. I've been deploying successfully for months and this deploy contained a merely cosmetic change to my app so I think this is rather strange.

Hi @sam0x17, is this an error that involves this client library, google-cloud-ruby or one of its sub-packages, such as google-cloud-bigquery ?

[sam0x17]

When I re-tried the deploy it worked -- interesting

@quartzmo it involves deploying a rails app to app engine -- I'm not sure where to post so I posted here

@quartzmo feel free to close -- too bad app engine doesn't have a place to report issues like this

@sam0x17 You can report app engine issues on https://github.com/GoogleCloudPlatform/ruby-docker which is the Ruby runtime. That will at least be one step closer to the teams involved. (In this case, I don't know what the deal was with the error you saw, but if it corrected itself it might have been a momentary fluke in the service. I'll see if I can get some answers.)

@sam0x17 You can also try asking on Stack Overflow with the google-app-engine tag. If you get an answer, please link back to it from this issue, to help out any future person who comes across this issue in a web search.

ah ruby-docker -- totally forgot about that -- thanks @dazuma !!!
