We recently upgraded to Power BI Report Server on premises. We have a directory name "President's Office". While still on SSRS the was no issue with name. After upgrading we received an error when clicking on the ellipsis in the upper right corner of the folder. The error persisted for all subfolders.
The error reported is:
An error has occurred.
Something went wrong. Please try again later.
We removed the apostrophe and normal operation resumed.
