Describe the bug

Hi !
I'm trying to recycle a group connected site collection with the method context.GetSiteCollectionManager().RecycleSiteCollectionAsync(siteUri). The API calls always end up with a http 500 error : SharePoint Rest service exception with no further details.

I first thought it would be a permission related issue, but I ended up giving every possible permission to my app, including the "Sharepoint administrator" and "Group administrator" roles, and I still get the error. I'm using app-only authentication with a certificate.

Do you know if the endpoint has a issue for now ? Or I'm a doing something wrong ?

Steps to reproduce

1. Create a context with app only authentication (client ID + certificate)
2. Get the admin context
3. Try to delete a site with context.GetSiteCollectionManager().RecycleSiteCollectionAsync(siteUri)
4. See the error

Failing API call : POST https://mytenant-admin.sharepoint.com/_api/GroupSiteManager/Delete?siteUrl='https://mytenan.sharepoint.com/sites/hh'

Expected behavior

Site deletion successfull.
