Trouble importing Jurassic

Why do i get an error with this in c#:
FindTypedVariables(this, result, conditional: false, continueEncountered: ref continueEncountered);
and have to change it to:
FindTypedVariables(this, result, false, ref continueEncountered);

I don’t want to change the code, because it’s not mine. I’m using jurassic in my asset…

Looks like your coder has been a numpty and copied the constructor from the docs but failed to remove the ‘types’.
