It’s an ambiguity with “this function.” That is meant to refer to `readLastMessage`, but its position in the text makes it perfectly reasonable to interpret it to mean `deserializeMessage`.

You wouldn’t get an error if you called the underlying Message DB function with a category stream, but it most likely wouldn’t find any messages with that exact `stream_name` either.
