Return null on the error path for the iterator #7

Closed ammaraskar closed 3 years ago

ammaraskar commented 3 years ago

Saw some "builtin function returns value despite setting exception" errors.

As per the docs:

When another error occurs, it must return NULL too. Its presence signals that the instances of this type are iterators.

Oh sorry 🤦 I edited this very quickly with the github editor, it should have been our positions iterator not the linetable one.
