Renaming devices in intune via Powershell - powershell

Question

I am trying to write a PowerShell script that allows me to update all the names of our devices in Intune [430ish devices] to reflect our asset tags. When they were imported into our tenant, they were given the serialNumber of the device as their deviceName. All permissions for the API have been applied:
API Permissions:
Device Read
Device Read all
DeviceManagementApps.ReadAll
DeviceManagementApps.ReadWriteAll
DeviceManagementConfiguration.ReadAll
DeviceManagementConfiguration.ReadWriteAll
DeviceManagementManagedDevices.PrivilegedOperations.All
DeviceManagementManagedDevices.ReadAll
DeviceManagementManagedDevices.ReadWriteAll
DeviceManagementRBAC.ReadAll
DeviceManagementRBAC.ReadWriteALL
DeviceManagementServiceConfig.ReadAll
DeviceManagementServiceConfig.ReadWriteAll
User Read
This is the code as far as I can get it, but I am still getting the following error [I apologise for ugly or poorly formatted code, I have had no formal training, all learnt using google-fu!]:
# Setting variables for connecting to the MS API
$ApplicationID = "xxxxxxxxxxxxxxxxxxxxxxxxxxx"
$TenantDomainName = "contoso.com"

$Body = #{

Write-Host "StatusCode:" "$_.Exception.Response.StatusCode.value__"

}
}
Error response:
StatusCode: A parameter cannot be found that matches parameter name 'Body'..Exception.Response.StatusCode.value__
StatusDescription: A parameter cannot be found that matches parameter name 'Body'..Exception.Response.StatusDescription
StatusCode2: A parameter cannot be found that matches parameter name 'Body'..ErrorDetails.Message

I had similar problems some months ago manipulating intune devices from an powershell runbook over graph. In my case the json body was the problem. I had to define the body first as hashtable and then convert it to json. Try something like this:
# JSONPayload as hashtable instead of string
$JSONPayload = #{
"#odata.type" = "#microsoft.graph.managedDevice"
"actionName" = "setDeviceName"
"deviceName" = "$tag"
}
# Writing out to check if this is working correctly
$JSONPayload
# Converting $JSONPayload to an actual workable JSON
$convertedJSON = $JSONPayload | ConvertTo-Json
And then pass the $convertedJSON to your graph call as body:
Invoke-MSGraphRequest -Url $uri -HttpMethod POST -Content $convertedJSON -Verbose
EDIT:
You are calling the endpoint /deviceManagement/managedDevices/executeAction with the http method PATCH. According to this ms docs article you have to call the endpoint with the http method POST.
