Upload file is keep on giving faulted

Continuing the discussion from SharePoint custom activities documentation not available:

Upload file activity from SharePoint custom activity is suddenly not working. Giving faulted error.

Could you please give us more information about the error and parameters that are triggering it?
Some screenshots will be of great help too. Also, if the error is happening all of a sudden and before this activity worked previosuly I would suggest analyzing the input arguments and/or maybe any recent changes that happened to the project
