PBRS Oct/2020 Release update causes errors in Scheduled Refresh

 

Hi all,

 

After install the new release update of PBRS in a DEV Server, some reports are not beeing refresh with successfully:

 

SessionID: 12a473d7-3e18-4071-b4d4-3145543d99ff
[0] -1056505856: COM error: System.Core, A sequência não contém elementos.
[1] -1055784828: The database operation was cancelled because of an earlier failure.

The same report in May/2020 version is refreshing normally.

I already opened the report in Desktop October versioon, refresh all, save again e nothing changes.

 

Could be a bug in the release?

 

Thanks.

    The workaround will only work if you have not used the October 2020 Desktop version to open-edit-save the .pbix file directly in the server.

    The May2020 will refuse to open the file as it has been updated to the Enhanced Dataset Metadata Format..... Too late...

    Furthermore, you better have saved a copy of your reports already in production... If so, just LOAD from the server your previous .pbix file and it will run scheduled updates again.

    Then you can use May2020 version to make changes.

     

    Please fix the issue ASAP.... These things should have been tested before releasing the update....

    It is better to wait some more when structural changes are done better than this...

    Hi Luanrad,

     

    Can you let me know what is the type of datasource used by your report and the connection string(with identifying info removed).

     

    thanks

      Hi Boreki,

       

      thanks for you reply.

      The report source is MSSQL databases. 1 is ReportServer and the second is other with employees information, to merge UserDC information.

       

       

      Detailed error log:

        Hi Lúcio!

         

        Would you please also check the log prefixed with "asmanagedroot" for any exceptions around the same time and share here if possible?

         

        Thanks

    We are seeing the same thing when we try and refresh.  We will revert the desktop back to the May 2020 release.  Please fix ASAP.
