How to update a ContentType Field for a Modern SharePoint Page?

[myatix]

Hi All,

I am trying to create a PnP.PowerShell script to updates the "Audience" column under the Site Page content type, so that it is a required field rather than optional?

I tried the below but it doesn't work?

# Get Context
$clientContext = Get-PnPContext
 
# Give target content type name over here
$targetContentType = Get-PnPContentType -Identity "Site Page"
 
# Load target content type and content type fields
$clientContext.Load($targetContentType)
$clientContext.Load($targetContentType.Fields)
 
$clientContext.ExecuteQuery()
 
# Get required field from the target content type
# Mention field internal name or display name over here
$targetField = $targetContentType.Fields.GetByInternalNameOrTitle("Audience")
 
$clientContext.Load($targetField)
 
$clientContext.ExecuteQuery()
 
# Make content type field required
$targetContentType.FieldLinks.GetById($targetField.Id).Required = $true
 
# Update(UpdateChildren – bool), this value indicates whether the children content type(inheriting from this Content Type) needs to be updated. 0 = False, 1 = True
$targetContentType.Update(0) 
 
$clientContext.ExecuteQuery()

The script cannot find the field "Audience" even if I use the "_ModernAudienceTargetUserField" name???

Exception calling "ExecuteQuery" with "0" argument(s): "Column 'Audience' does not exist. It may have been deleted by another user."
MethodException:
