I’m trying to run a MongoDB query and return those records where a field is null (more specifically None in pyMongo). So it has to be equal to null.
I know this is not equal to:
{"firstName": {"$ne": None }}
I can’t find the equal operator in the documentation.
Thanks
{“firstName”:{ $type: 10 } } should give you what you want
