"Bad Request: invalid user_id specified" error when refunding star payments

[SaeedPoureshghi]

Description

I'm encountering a Bad Request: invalid user_id specified error when attempting to call the refund star payments endpoint. I've double-checked the user_id and confirmed it is correct.

Steps to Reproduce

1. Call the refund star payments method with a valid user_id
2. Receive error response: "Bad Request: invalid user_id specified"

Expected Behavior

The refund should process successfully with a valid user_id.

Actual Behavior

The API returns an error stating the user_id is invalid, despite verification that the ID is correct.

[levlam]

The error "Bad Request: invalid user_id specified" can be returned only if you didn't specify the parameter user_id at all (or explicitly specified it as an invalid integer).

[SaeedPoureshghi]

Yes , I know. I have double checked. user_id provided and is ok.

[levlam]

No, user_id is not sent in the request. It is the only way to receive the error.
