Update-mgdevicemanagementmanageddevice -devicecategory

Does the cmdlet work ?
because can't make work with -bodyparameter or -devicecategory, eveytime he result with an error
$Params = @{ DeviceCategory = @{ "DisplayName" = "$NewCategory"} } | ConvertTo-Json try { # Changer la category Update-MgDeviceManagementManagedDevice -ManagedDeviceId $Device -BodyParameter $Params

I cannot make it work either with the built-in cmdlets.

Update-MgBetaDeviceManagementManagedDevice -ManagedDeviceId $myIntuneDevice.Id -DeviceCategory $category
Update-MgBetaDeviceManagementManagedDevice : Cannot apply PATCH to navigation property 'deviceCategory' on entity type 'microsoft.management.services.api.managedDevice'.
Status: 400 (BadRequest)
ErrorCode: ModelValidationFailure

Update-MgBetaDeviceManagementManagedDeviceCategory -ManagedDeviceId $myIntuneDevice.Id -Id $category.Id
Update-MgBetaDeviceManagementManagedDeviceCategory :
Status: 404 (NotFound)
ErrorCode: UnknownError
Date: 2023-10-03T17:03:16

The only way to make it work is like this:

$body = @{ '@odata.id' = "https://graph.microsoft.com/beta/deviceManagement/deviceCategories/$($category.Id)" }
Invoke-MgGraphRequest -Method PUT -Uri "beta/deviceManagement/managedDevices/$(myIntuneDevice.Id)/deviceCategory/`$ref" -Body $body

This one work for me :

Update-MgBetaDeviceManagementManagedDeviceCategory -ManagedDeviceId $Device -BodyParameter $BodyParams

With the new category in the body parameter

Facing the same issue, I could make it to work using @geoced's recommendation.

I think the cmdlet should really be worked on more seriously as there's tons of limited/confusing functionalities which make it extremely unreliable to use with automation. The documentation is also horrible, and it feels whoever is writing this has no touch point with whoever is designing the graph APIs (some of which are also insanely weird and non-standardized, IMO)
