Mobile Reports Publisher - Power Bi report Server Problem

Hi,

We have some Mobile Reports (.rsmobile suffix) was opening properly on our Power Bi Report Server.

I upgraded Power Bi Report Server with last version (15.0.1111.115) last week.

After upgrading server, I could not open mobile reports. When I click report icon, server downloads it's file.

When save report from SQL Server Mobile Report Publisher to our report server, I get error.

Log file error is that:
