Jade plugin not working with IntelliJ 2018.1

When a jade file is opened the error log shows the below error, copy and paste stops working in IntelliJ and files don't open instead you just get the Loading text. Hopefully this will be fixed soon as all our templates are in Jade and we have had to turn the plugin off which means debugging the templates as plain text - which is quite hard.

Error from IntelliJ log:-
