Try checking the details about this error or behavior under the Event Viewer → Application (before the error, during the error, and after the error).

Hi @Rama_Thota,

The issue appears to be related to UiPath Executor rather than the workflow itself.

As an initial troubleshooting step, try clearing the temporary/cache files, restarting the machine, and checking whether there is sufficient disk space and available memory.

Also, could you check the Windows Event Viewer for any UiPath.Executor crash details?

Thanks

  • Stop this service from Taskmanager and try to restart then check how it is executing

And if still that doesn’t work try below

Go to
Control Panel >> Programs >> Programs and Features >> check for UiPath and click on change it will ask re installation/update the latest version.

Hi @Rama_Thota,

A few things you can try:

  1. Check Event Viewer → Windows Logs → Application for any UiPath.Executor.exe or .NET crash details.
  2. Open Task Manager and verify whether any UiPath.Executor.exe processes remain running after the job completes. If yes, end them and test again.
  3. Run a Repair on the UiPath installation from Control Panel → Programs and Features → UiPath Platform → Change → Repair .
  4. Verify that Robot, Studio, and activity package versions are compatible and up to date.

Happy Automation!

I could see there are always two kind of errors as attached in Event Viewer whenever we encounter this popup.

Hi @Rama_Thota,

Are you facing this issue with a particular process? Try running the process in Debug mode and check whether any argument is empty.

As per the event log, this occurs due to an argument with an empty or invalid expression. Please check your workflow arguments (Input/Output/InOut), especially any arguments that were recently modified or are not mapped correctly after the update.

Thanks

Hi @iampnkz,

Yes, it is occurring to particular process, but when we see in debug mode and validate the process there were no errors reported except one warning that is

Bad IL format. The format of the file ‘D:\Users\xyz.nuget\packages\UiPath.database.activities\1.7.1\lib/net5.0-windows7.0/runtimes/win-x64/native/Microsoft.Data.SqlClient.SNI.dll’ is invalid.

As you mentioned we will also verify if there are any arguments with an empty or invalid expression.

Thanks!

Event ID 1026 (.NET Runtime): Says null value issue (ArgumentNullException). This is issue your workflow is trying to use an uninitialized or null variable.

Event ID 1000 (Application Error): This occurs when UiPath Executor stops due to the unhandled exception.

Basically 1000 occurs because of it 1026 issue. so, add null checks and verify exception handling logic once.

It seems that the issue comes from the version of the UiPath.System.Activities package.

Upgrade the robot version to something that is supported (23.10.x, 24.10.x or 25.10.x)

Installers:
https://download.uipath.com/versions/23.10.15/UiPathStudio.msi
https://download.uipath.com/versions/24.10.22/UiPathStudio.msi
https://download.uipath.com/versions/25.10.12/UiPathStudio.msi

Upgrade the UiPath.System.Activities package in your project to match the latest version in its major version of the robot (e.g., 24.10.7 for robot/studio 24.10.22)
