I'm trying to update (patch) the deviceNames for all my Intune managed devices using the output from a Compose action in a loop. I'm having a hard time locating any content where someone has used the HTTP action to patch Graph properties. This is what I have in the HTTP Patch action so far:

And this is the error I'm receiving:
{
"_version": 3,
"Message": "An error has occurred - Operation ID (for customer support): 00000000-0000-0000-0000-000000000000 - Activity ID: 3d757357-2f63-4ce4-9813-b21e3fb3eda7 - Url: https://fef.amsua0602.manage.microsoft.com/DeviceFE/StatelessDeviceFEService/deviceManagement/managedDevices('2ff30ec9-038b-421c-9127-d6acc3be216b')?api-version=5022-12-12",
"CustomApiErrorPhrase": "",
"RetryAfter": null,
"ErrorSourceService": "",
"HttpHeaders": "{}"
}

I would greatly appreciate some feedback on this. Thanks!
