Hi, I’m encountering this error recently.

The image shows a "Unable to start execution" error message in a UiPath workflow, indicating that an object reference is not set to an instance of an object. (Captioned by AI)

Initially, I assumed it was specific to my project, but after creating a new REFramework template, the same error appeared there as well.

please help me understand how to resolve this issue? Any assistance would be greatly appreciated.

Thanks in advance!

Close the studio, delete the project.json file for this process and reopen the process.

Hey @jai_kumar2 kindly validate your project might be there are some null variable or arguments is being initialize which cause these error. so in your studio in the ribbon tab there is a validate action run this it will give more details .

The image shows a screenshot of a software interface, specifically Google Workspace Scope in UiPath, highlighting a dropdown menu under the "Analyze Project" settings, along with options to create and write into a spreadsheet. (Captioned by AI)

Hi @sppal.c @singh_sumit thanks for reply, but this issue is occurring even in a newly created template.

No no don’t create any new template just open your project in the ribbon tab as i mentioned in the above screenshot click on that and it will give you the list details something like this.

The image shows an error list window from a programming environment, displaying three validation errors requiring values for "Folder," "SpreadSheetID," and "DataTable" in the Main.xaml file. (Captioned by AI)

@jai_kumar2

As a first step try to go to c:/users/username/.nuget and delete the packages folder

@jai_kumar2,

It looks like more of Studio issue than the template.

  1. Try clearing the temp files
  2. Restart the studio
  3. Restart the machine

Please restart the studio. Also, try to update UiPath Studio version.
