does not have permission

[lukeyu]

Hello, I have already authorized these permissions for my application. Initially, I was able to obtain the order's fulfillment, but after a while, when I tried to call it again, it gave an error saying, "The api_client does not have the required permission(s)." May I know what could be the reason for this?

My API version is 2023-07.
