General exception when inviting users to access a file in a SharePoint Site

Mario Vitale 0 Reputation points

I have a problems using the MS Graph API Add Permissions on a SharePoint site.

My application uses an app registration with the Sites.ReadWrite.All permissions allowing to upload and share a file using the Graph API. The SharePoint configuration is as follows:

sharepoint config

I encountered 2 issues while developing. The first is that when the "Allow only users in specific security groups to share externally" flag is enabled, the app registration can no longer share files, even if it is present within one of the allowed groups. Removing the flag restores the sharing functionality.

first error

The second problem is related to sharing itself. Currently, sharing only works with Microsoft Work Accounts. If a "non-Microsoft" account is used, I receive a 500 error with code "generalException" and message "An unspecified error has occurred.".

I opened the same issue on OneDrive api docs. What can I check? Are there any configurations in the tenant or in the API that I can verify? Thank you
