Issue uploading some .pbix files to report server

[Anonymous]

I am getting an error when trying to upload a .pbix file to Power BI report server. It is only this report and one other that give the error, all of my other files upload and refresh just fine. All of my reports are created on power bi desktop RS and all connect to the same database. Any ideas why one would fail and others are fine?

You probably should check the log files on the server. They may have more information about the cause of this issue.
