Welcome to our UiPath community.

Can you please share screenshot of the flow where you are getting this error.

Hi,

This is the screen shot. I do not see any validate error in the flowchart. I also share the read CSV activity. I am not sure whether I setup correctly or not.

Default value should be New DataTable or keep it blank for InspectionNumber variable and then check once.

Hi Yoichi,

I review this article but it do not mention how to resolve the issue. It just say recreate it again. In my flowchart. I do not see any validation error. I do not know what is wrong.

Thank and best regards,

Hi,

In the above post, he said

The workaeound was to edit the xaml file and remove/comment out the references to the pointer. In my case “point”.

So can you try to edit xaml file directly? Or can you share your xaml file?

Hi,

Thank you for sharing. In my environment, I couldn’t reproduce your issue. So, I guess there might be something wrong in your environment.
For now, can you try the following steps?

  1. Close UiPath Studio
  2. Remove (or move for enable to restore later) files/folder under c:\Users\(accountName)\.nuget\Packages
  3. Remove (or move for enable to restore later) files/folders under C:\Users\(accountName)\AppData\Local\NuGet\v3-cache
  4. Open UiPath Stuido and your project

Hi,

Which version of Studio do you use? If you use lower version, can you try to update to the latest : 22.4.0 (stable)?

Hi Yoichi,

I try to recreate the same flowchart in new project without any change. Now it is working fine. It is strange and I do not know why UiPath show this error. Anyway, thank you for your help.

Thanks and best regards,
