Hi,
This could be happening if you're storing the string form of keys in
your db entities (str(entity.key())). You may need to run a process
to cleanup / convert your data, or you could figure out where this is
coming from and add handling in there.
A very simple example of the conversion logic this:
clean_key = db.Key.from_path(*bad_key.to_path())
Note that if you use namespaces, you'll have to set that as well.
