Many thanks to Rahul who jumped in and addressed the issue for my affected project.
It turns out, this was another manifestation of this issue <https://issuetracker.google.com/issues/35899754> that needs to be addressed. (Basically, Google rolled out a new runtime to a percentage of the running instances, there was a problem with the new runtime so requests to the canary instances fail and I had to realize it and inquire, and then Google puts all the project's instances back to the old runtime until they address the issue and try again)…. Please star the issue before it happens to you, it is rare but when it happens is not fun... > > Hello, > What is your app-id where you are seeing this? > Thanks, > ~Rahul. > > On Tue, Oct 31, 2017 at 1:37 PM, PK <p...@gae123.com > <mailto:p...@gae123.com>> wrote: > Many requests fail, usually Ajax calls but I just got one in the UI.
