[App Store Connect API] Failed to list sandbox testers and clear purchase history by 403 forbidden error

When attempting to list sandbox testers and clear purchase history through the App Store Connect API, the API Server returns a 403 forbidden error. I have set a correct token in the Authorization header, allowing me to list apps, users and bundleIds. Furthermore, I was able to list sandbox testers and clear purchase history successfully until two weeks ago.
