Google Workspace :- Cannot create unknown type variable

[indiedev91]

Hello everyone, I’m posting on behalf of my colleague who is encountering the following issue.

She is using UiPath.GSuite.Activities Version: 2.5.6, and her Studio Version is 20.10.3.

The error she’s facing is:

System exception at initialization: Cannot create unknown type '{http://schemas.microsoft.com/netfx/2009/xaml/activities}Variable({clr-namespace:UiPath.GSuite.Models;assembly=UiPath.GSuite}GmailMessage[])'. at Source: System.Xaml

The interesting part is that the error doesn’t occur in debug mode but shows when run from Studio, Assistant, or Orchestrator.

Copy all the folder in %USERPROFILE%\.nuget\packages from PC of Studio to PC of Robot. Install "local activity feed" to robot using installer if not in previous. F…
