[Python] I am attempting to use Django Ninja for the first time and running into a strange...

I cant quite understand error I am receiving. I am simply trying to setup a model schema for my model. I am an old Django hand but ninja is new for me. What am I doing wrong here? Would love some help and feedback.

My model is this

class Program(models.Model):
mentor = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
description = models.TextField()
start_date = models.DateField()
end_date = models.DateField()
attendees = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name="attendees")
participants = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name="participants")

created_on = models.DateTimeField(auto_now_add = True)
updated_on = models.DateTimeField(auto_now = True)


My api.py has the following definition

class MentorOutSchema(ModelSchema):
class Config:
model = Program
model_fields = [
"mentor",
"description",
"start_date",
"end_date",
"attendees",
"participants",
]



My endpoint is this

@router.get('/programs')
async def mentor_programs(request, response=list[MentorOutSchema]):
return Program.objects.filter(mentor=request.user)



When I start the server, I get the following error

@router.get('/programs')
