Modern Team Site Creation - Error - Suddenly the response for Site URL is Null

Brass Contributor

Modern site creation is suddenly failing today due to response coming back with Null.



 We have been using SharePoint’s REST API call to create a modern team site and the solution has been running for almost a year now without any problem. The API used: /_api/GroupSiteManager/CreateGroupEx (HTTP/1.1)




This solution was discussed with Microsoft an year ago recommended by MS as a supported solution.


Issue/Root cause:

This morning we have noticed that the API call returns following response with Null for site url:



Ultimately the site will get created but it takes fair amount of time and our process will error out due to null response.


Any directions is really helpful.

@Vishwanatha Nayak I am receiving this error just now. Looks like it started appearing since this morning. We can't rely on this API I believe. But there is no replacement at the moment to create O365 group from SharePoint. 

Same issue using pnp CSOM.


About half of our teamsites, created from a signal from our CRM, are failing since between the 19th and 21th of june.
