I runned schemathesis on django-ninja-jwt, it found several problems:

Reproducer:

from ninja_extra import NinjaExtraAPI
from ninja_jwt.controller import NinjaJWTDefaultController


api = NinjaExtraAPI()
api.register_controllers(NinjaJWTDefaultController)

and a test case:

import schemathesis
import pytest

from api import api

schema = api.get_openapi_schema()

schemathesis.experimental.OPEN_API_3_1.enable()
schema = schemathesis.from_dict(schema)


@schema.parametrize()
def test_api(case: schemathesis.Case, live_server):
    case.call_and_validate(base_url=str(live_server))
