Gmail account issue in StudioX

I have been trying to use activity “Use Gmail” in StudioX for reading email and saving attachments. I have also successfully added gmail account however, on running the process, i get the following error:
Something went wrong with Email.
Activity Use Gmail (Gmail Application Card) failed:

The card is not configured or value is not available at design time. Unable to find a constructor to use for type UiPath.Mail.Google.Models.GoogleAccount. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute. Path ‘AccountNo’, line 1, position 13.
Can anyone help me with this?


Have you provided all the required details like:

  1. Server and port
  2. Log on details

If not provide all the required details… And also check for the packages if any new updates .


I think the login details are automatically taken. I have updated the packages too. But still not working.

Hello @Narayan_Prajapati
In the workspace have you configured the Gmail APi and created the authenticated keys properly?
