Google AppEngine backups reporting ApiTemporaryUnavailableError

When trying to backup the datastore from the DataStore admin page, backups fail with and error for both blobstore and cloud store targets:

Callstack for cloud store:

Seems to be a problem with the underlying files API which is out of our control. Anyone come across this and have a solution or workaround?

I think this may have to do with the fact that the files API is deprecated.

I had the same error trying to push a mapreduce pipeline to the blobstore (as George-Bogdan is having). I decided to finally do the switch I have been avoiding (switching to the GCS client library). Once I finished the switch, my tests have been conclusive, this works properly.

It seems like it's a transient issue on the Google side. But since the Files API is deprecated, I feel safer using the library they actually suggest using now
