Thanks for the suggestion @indra but that didn’t seem to work. I deleted the JSON file I had associated with my project and then double clicked the GetAppCredentials xaml in the Framework folder. It then creates a JSON file in that folder but I still have the same red error messages.
I then tried deleting that JSON file and opening other workflows in the same project creating other JSON files but that didn’t help either.
Have you upgraded to 18.3?
Could it be anything to do with missing packages that weren’t added with the 18.3 update (I don’t know just clutching at straws)
It seems to be having issues with the following 3 activities
if I go to my activites window and type credential there is a Get Credential activity but if I look in the properties window it’s UiPath.Core.Activities.GetRobotCredential
I’ve got a feeling that this may have changed in the update (but I can’t see as I don’t have the old version any more)
