Reporting Error when SCOM 2019 upgrade to UR4

Hi Guys,

The SCOM 2019 UR3 upgrade to SCOM 2019 UR4 and check on Report role, on custom design reports, got Cannot Execute Report error.

Note: The following information was gathered when the operation was attempted. The information may appear cryptic but provides context for the error. The application will continue to run.

System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.EnterpriseManagement.Mom.Internal.UI.Console.ReportForm.RunReportJob(Object sender, ConsoleJobEventArgs args)

If a custom report does not require specified parameters, the report can be generated.

An error will occur if a parameter needs to be specified.

I have reference to ,It says that there are two DLL files that need to be updated from Microsoft. Where can I get them?

    You can upgrade to directly to UR5. Each of the update rollups are cumulative. Simply means you do not have to apply them in order, you can just install the latest update, or in your case, UR5.

    Please read the Know Issues section before you start. Remember to backup any files you are going to edit before editing them.

    Issue #1. You may not see three "sandbox" words during the search of the "main.js" file, only two. If that is the case, edit the second as mentioned in the text of the issue.

    There is also a "Hotfix" available for Linux if you monitor that in SCOM: KB5028684

    Hope this helps,

    I suspect that these two dll files, did not publish out. I recommend upgrading directly to UR5 and see if that fixes this.

    What I'm worried about is that updating to UR5 still doesn't solve the problem. Does anyone have better suggestions?
