[BUG] pydantic.errors.PydanticSchemaGenerationError

[realmokhalili]

I get this error when setting response to be list

**Versions **

• Python version: 3.13
• Django version: 5.1.4
• Django-Ninja version: 1.3.0
• Pydantic version: 2.10.3

from ninja import NinjaAPI
from typing import List


api = NinjaAPI()




@api.get("/yo")
def yo(request, response=List[int]):
    return [1,2,3]

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'typing._GenericAlias'>. Set arbitrary_types_allowed=Truein the model_config to ignore this error or implementget_pydantic_core_schema` on your type to fully support it.

If you got this error by calling handler() within __get_pydantic_core_schema__ then you likely need to call handler.generate_schema(<some type>) since we do not call __get_pydantic_core_schema__ on <some type> otherwise to avoid infinite recursion.

Please try

@api.get("/yo", response=List[int])
def yo(request):
    return [1,2,3]

instead.

@uweschmitt will do that now, been bit busy with life as well as a major build taking my attention away from the other builds i have open. Thank you for the suggestion!!!! 😊
