Graph get /devices returning text response instead of json since 01/2024

Question

Graph get /devices returning text response instead of json since 01/2024

Sarah Thompson 25

We have been using the call GET https://graph.microsoft.com/v1.0/devices to return all of the devices on our tenant for over a year now with application credentials and it has been working great. The last time it worked properly for us was on Jan. 2, 2024. Now the api call returns a text body instead of a json response. Any idea what happened here or how to fix? Looks like there was a graph api update around the same time. Please help! Ty!

Could you please provide the following details?

Are you receiving an error response?

Are you using the Graph SDK? If so, what is the version? Have you tried updating the version and calling the API again?

can you share the response header values, especially the content type?, have you tried content-type with 'application/json' header?

$uri = "https://graph.microsoft.com/beta/deviceManagement/reports/microsoft.graph.getConfigurationPoliciesReportForDevice" $response = $null $response = Invoke-MgGraphRequest -Method post -Uri $uri -Body $body -OutputType Json -debug -verbose

I have the same issue, request JSON but...

VERBOSE: received 11397-byte response of content type text/plain

DEBUG: POST https://graph.microsoft.com/beta/deviceManagement/reports/microsoft.graph.getConoliciesReportForDevice

PS C:> $response.GetType().Name
