It doesn’t even let me debug the file for some reason. I have reset the program and have tried to look into certain problems. Also this has not happened before

This error. All of my values have been filled too.

@dolx

As per error one of the values you should provide is not provided or is null…

Specifically please check the activity which is failing and see what is the null value or empty value

Cheers

Hi @dolx
The error message “Value cannot be null. Parameter name: PipeName” in UiPath indicates that a parameter named “PipeName” is being passed with a null value, which is not allowed. This error typically occurs when working with activities that involve named pipes, such as the “Start Process” or “Invoke Workflow File” activities.

  1. " Verify that the “PipeName” property or any related parameters are correctly configured and not set to null.
  2. Validate input values: If you are passing arguments or variables as inputs to activities that use PipeName, ensure that these values are not null. Validate and initialize the inputs before using them in the activity.

Hope it helps!!

@dolx

Yeah you have created one argument can you please check whether the argument was properly assigned to a variable.

Regards

You can attach you xaml here if it is not having any sensitive data.
