[Vuejs]-Django REST API allows post from Swagger, but not from postman or vue form using axios

The problem was in the model not the gui.

Here is the correct row in the model:

param2 = models.CharField(max_length=200, blank=True, null = True, default = 'N/A' )

in the other models that were working, I had both blank and null set to True like here, when I updated the offending model to add blank=True, everything was back to normal, the error messages were misleading.
