[Solved] Found this error message (DI/DO: Some wire Assignments are defective.)

Good Day,
I am using camera D15 and found this error message - DI/DO: Some wire Assignments are defective. May I know how to solve this?

Hi, this happens when the camera has connected an IO module and in the admin menu, cable assignment you have selected some IO output. To solve it, access to cable assignment and select none.
