 Error in OneDrive Sync Client



If any info needed i can share.


The error says that scope id is null as you see. What is scope id and why it null.

I tried OneDrive Sync different web applications and different my site host sites but the result is same.


The important clue is this happens only in Turkish people. That's way i think it's about language or regional settings. Bu all of my environment is installed and configured with English locale settings.


Any help appreciated.
