Hi,
In this morning, I confirmed I could reproduce the issue in my environment (Studio22.4.6+Windows C# project) as the following.
08:27:20.1476 => [ERROR] [UiPath.Studio.App.Logging.OutputLogger] [57] Read PDF With OCR: Expression Activity type 'VisualBasicValue`1' requires compilation in order to run. Please ensure that the workflow has been compiled.
However, after I upgrade / downgrade some packages several times, the issue suddenly doesn’t occur. And I cannot reproduce the issue after that even if I restore version of activities package.
Regards,
