Hi, I couldn't find an earlier question about this, so could someone explain why: “Querying for a value of None on a repeated property has undefined behavior; don't do that.”[0]
This sounds very weird. Is this some curiosity with the datastore itself, or just some complication within the NDB library? I've used NDB for years, but I learned about this issue just now as my friend spotted the peculiar notice. I've got no idea whether this has caused undefined behaviour in some of the systems I've worked on as I would've *never* expected this kind of behaviour. Though, if NDB raises an exception about this, then I can be sure that I haven't encountered this in practice.
