Move SSRS reports to existing PBIRS


I am building out a new server to replace our SSRS 2012R2 server, and in testing I am noticing errors in the RSOffice_xxxxx.log.  (see below).  I haven't yet been able to see what is causing this as I can export a document to Excel.  However, I need to get this cleaned up before we can migrate to the new server.


Thanks for your help.

I thought I would also add that I have the version of the report server installed.


Thank you very much.

I am not sure that I like the solution that I have found, but...  I placed the user for the Power BI Report Server in the admin group on the server and now everything is running without errors.


Any other suggestions?
