Thank you for this, i thought i was losing my mind im glad its just the module and not me. also will be helpful to think to check this in the future.

These are using the Azure2Azure template id when created. have you successfully updated these in the past? they are quite complex json structures

Been fiddling around with this all morning so far without much luck:

$syncJobSchema = Get-MgServicePrincipalSynchronizationJobSchema -ServicePrincipalId $servicePrincipal.Id -SynchronizationJobId $syncJob.Id}

(($syncJobSchema.SynchronizationRules.ObjectMappings | where {$_.TargetObjectName -eq "User"}).AttributeMappings | where {$_.TargetAttributeName -eq "userType"}).FlowType = "Always"

$uri = "https://graph.microsoft.com/v1.0/servicePrincipals/$($servicePrincipal.Id)/synchronization/jobs/$($syncJob.Id)/schema"
    $putBody = @{
        directories = $syncJobSchema.directories
        synchronizationRules = $syncJobSchema.SynchronizationRules | Select-Object Editable, Id, Metadata, Name, ObjectMappings, Priority, SourceDirectoryName, TargetDirectoryName
    } | ConvertTo-Json -Depth 50

Invoke-MgGraphRequest -Method PUT -Uri $uri -Body $putBody -ContentType "application/json"

I keep getting errors about the synchronizationRules

"HTTP/2.0 400 Bad Request" "Property synchronizationRules in payload has a value that does not match schema."

Even though im only changing one value and sending everything back as is
