I got the following error:

I immediately called the same script and it worked with no issues.
It raises another question: Why is the schema downloaded every time when it cannot change (as it is frozen to for each version)?

Hello,

Thanks for the report. It looks like you had an issue retrieving the schema there. I wouldn't be too concerned if it happened just that one time, as it sounds like some sort of connectivity issue.

Your question about downloading the schema every time is a valid one. It's probably because caching is disabled by default--that was a decision made quite some time ago for App Engine support. It probably doesn't make sense anymore, so we'll look into changing that.
