decorator error message is very confusing

[asukaminato0721]

Describe the Bug

Argument (self: Self@ExternalApiTemplateListApi) -> tuple[dict[str, bool | int | list[ExternalKnowledgeApiDict] | None], int] is not assignable to parameter view with type (@_, str, ParamSpec(@_)) -> @_ in function controllers.console.wraps.with_current_tenant_id

all I need to do is

def get(self): ...

to

def get(self, current_tenant_id: str): ...

so the error message should tell me I missing a str parameter at definition.

maybe the definition also can help a bit.

def with_current_tenant_id[T, **P, R](
    view: Callable[Concatenate[T, str, P], R],
) -> Callable[Concatenate[T, P], R]:
    @wraps(view)
    def decorated(self: T, *args: P.args, **kwargs: P.kwargs) -> R:
        _, current_tenant_id = current_account_with_tenant()
        return view(self, current_tenant_id, *args, **kwargs)
    return decorated

This makes sense the current error is surfacing a low-level type mismatch instead of explaining the missing parameter in the original function signature. I’ll take a look and see if we can improve the decorator-related diagnostic to report the missing current_tenant_id: str argument more directly.
