[Bug] Unexpected error with Azure Update Management integration
When opening the Updates tab of any managed system we receive the following error when WAC attempts to query if the system is managed by Azure Update Management:
Unexpected error occurred while detecting Update Management setup: n is null
All of the systems managed by WAC in our installation are registered with Azure Update Management.
On navigating to the Updates page a pop-up appears for authenticating to Azure AD which does appear to succeed. If we use browser developer tools to monitor the network traffic we can see the GET request to login.microsoftonline.com return a 302 response with a response cookie setting various values.
