@Swahela Mulla Thanks for posting in our Q&A.
For this issue, I have tried it in my environment. It shows the same error as yours. Graph issue is more related to develop scope. Honestly, I'm not familiar with it and the resource I get is limited. Given this situation, it is suggested to create a Premier or Unified support ticket to get more help. Here is the support link:

Hope everything goes well with you.
