I keep getting this error on Orchestrator but not while running manually

@rodrigo.simao,

It happens mostly due to incompatibility between Studio version and Robot version differences.

Check these few threads for more understanding and solution.

Could not load type 'System.Activities.TextExpressionBase`1' from assembly 'UiPath.Workflow, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null'

If you are using any package which is higher than any available in Enterprise version then it won’t work. Don’t use beta versions in Enterprise versions. If you lower the versions available to match with Enterprise and publish, it will work. Uninstall community version studio and install Enterprise dev studio and link with that Enterprise cloud orchestrator to resolve the issue. Enterprise studio is 2023.4.4.

Could not load type 'System.Activities.TextExpressionBase`1' from.....Error running unattended robots from orchestrator

From what I have tested, anything published from studio 23.10 breaks on 22.10 robot, even if packages should be compatible. My colleague published the exact same project from a 23.4 studio and that did work on the 22.10 robot.

Thanks,
Ashok
