An error occurred when attempting to save the report to Power BI Report Server

[RobertXiong]

Recently I downloaded the Newer Power BI Desktop (RS) (Version: 2.112.1421.0 32-bit (January, 2023)) and Power BI Report Server (on-premise) (Version1.15.8377.1837(September 2022)) , the both softwares are from same downloading page, they both supposed to be compatible each other. 

I opened reports with this new Power BI Desktop and modified and saved to local folder, that's no problem, but when I saved as to report server, the error message popup as below

so I opened the report server log file RSPortal_2023_05_10_10_34_01 

I found this message "2023-05-10 11:24:31.5902|ERROR|122|library|Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ItemNotFoundException: , Microsoft.ReportingServices.Diagnostics.Utilities.ItemNotFoundException: The item '/ReportTest/PowerBIRS-ParkingProcessPayment' cannot be found.;| RequestID = s_42ce677a-1b96-4858-b1a5-d03b608fb862" 

who knows how I can solve this problem?

Thanks in advanced.

Thanks a lot, I downloaded desktop and report server software again and made sure they were compatible, right now it works.

You cannot use a newer version of Desktop with an older version of the Server. The server will not understand a new file format that has changed since it was compiled. You can use older versions of desktop with a newer server, but not the other way around.

You need to use a version of Desktop that is the same or older than the server version.

You may be able to recover your existing report using one of the techniques in this post Power BI Report Server – fixing “Can’t upload this report” – Random Procrastination (gosbell.com)
