How to troubleshoot 'Bad Request' error when using 'startswith' to filter groups in Microsoft Graph API?

Question

I'm using the following endpoint to query the Microsoft Graph API, tracking changes by delta and filter groups by displayName using 'startswith':

https://graph.microsoft.com/v1.0/groups/delta?$select=id,displayName,members&$filter=startswith(displayName,'test-')

However, I'm receiving a '400 Client Error: Bad Request' for the URL. Can anyone recommend any troubleshooting steps or solutions?

Hello @Sameh Tawfik (MiddleEast) ,

According to the Microsoft documentation https://learn.microsoft.com/en-us/graph/delta-query-overview#optional-query-parameters, we can track changes to groups filtering only by object ID. We can't filter by using displayName. Please check below image.
