How do I fix issues with Django serializers?

I'm having trouble with my Django serializer. It keeps throwing validation errors.

Validation errors can occur for various reasons. Can you share the specific error message you're seeing?

It says 'This field may not be null' for a field that I thought was optional.

It sounds like the field is required in your serializer. Check if you've set required=False for that field in your serializer definition.

I did set it to optional, but it's still not working. What else could be wrong?

Make sure that the model field itself allows null values. If the model field is set to null=False, the serializer will enforce that.

Ah, I see! I need to change the model field. Thanks for the help!
