Trying to use powershell to get a list of planner plans associated with groups

Question

I am trying to use graph to get a list of planner plans assocaited with each Office 365 group.

I have configured my AzureAD app with the correct permissions per documentation. Specifically Groups.ReadWrite.All.

I used '$AccessToken = (Get-PnPGraphAccessToken)' to get and store my AccessToken.

I can issue statements to return group information except for when it comes to plans.

$headers = @{ Authorization=("Bearer " + $AccessToken) }
$uri = "https://graph.microsoft.com/beta/groups/{groupid}/planner/plans"
$webRequest = Invoke-RestMethod –Uri $uri –Method Get -Headers @{Authorization = "Bearer $AccessToken"} -ContentType "application/json"

I am getting the following error:

Invoke-RestMethod : {
"error": {
"code": "UnknownError",
"message": "\r\n\r\n\r\n\r\n401 - Unauthorized: Access is denied due to invalid credentials.\r\n\r\n\r\n\r\n\r\n\r\nServer

"client-request-id": "7081a605-7db0-4312-a74a-8475aa8fdd3d"
}
}
}

Any help would be appreciated!

Answer 1

• The error is telling that you havent passed the correct credentials to perform the request. So re try the code with correct credentials and see if it works.
• Just to isolate the issue you can repro the above graph api in Graph explorer or postman with right credentials and observe the results.
