    Previously working "Convert Image to PDF" smart service fails after plugin upgrade to v2.4.0 on 22.1 cloud environment.

    Using the "Convert Image to PDF" smart service to convert a tif to pdf.

    Delete plugin and re-added. Same error occurs.

    Process model fails with an error of "Convert Image to PDF   An error occurred in executing an Activity Class."

    The logs show the following:-
