Graph API error 503 serviceNotAvailable when getting item from SharePoint site in Power Automate

I am trying to use Microsoft Graph API in Power Automate where I make calls out to perform some actions. I have been successful with all Graph calls up to this one where I get a 503 serviceNotAvailable error.

The call I am trying is below

GET https://graph.microsoft.com/v1.0/groups/b40e54ac-5626-xxxx-xxxx-xxxxxxxxxxxx/drive/root:/filepath.docx

If I paste this directly into Graph Explorer on the Graph API site it works fine so I am happy that the call is syntactically correct.

I can't get the call to work through Power Automate. I also have tried this through Postman and am getting the same 503 error.

{
  "error": {
    "code": "serviceNotAvailable",
    "message": "The service is not available. Try the request again after a delay. There may be a Retry-After header.",
    "innerError": {
      "request-id": "87725851-77fb-xxxx-xxxx-xxxxxxxxxxxx",
      "date": "2020-03-01T16:55:43"
    }
  }
}

Permissions in my app registration are

Am pulling my hair out ... and there's barely anything left!

If you remove "Group.Create" permission completely and test, it should work.

Seems it doesn't like "Group.Create" with "Group.ReadWrite.All"

If it works in Graph Explorer, but doesn't in Postman. That typically means that your access token in Postman is not correct.

Have you looked at the Postman collection I put together? It puts on rails fetching the access token based on your application id and secret. https://learn.microsoft.com/en-us/graph/use-postman

With regards to PowerAutomate. How are you entering the application id and secret for the the flow to get the application access token? We do have a tutorial here from start to finish to show the approach we recommend here https://learn.microsoft.com/en-us/graph/tutorials/flow
