Gulp Uglify Error unable to minify JavaScript

Question

Yes - I am tumbling weed! I'm no code nerd but managed to come so far.

I have been able to "gulp" for a long time but suddenly I can't. If anyone could point me in the right direction. Have been googling last few days without luck...

Tried to reinstall web-app. Tried to look for type errors. Tried to install pump (so I could find errors - didn't manage to install correctly I think). Tried to figure out if it could be something to do with ES6 > ES5 - so tried to revert - w. babel...

Anyways any help would be great, Thanks

Ok used the good old "ruled out" method.. Found out it was an old Owl Carousel (V 1.3.4) plugin causing the problem... I guess at some point updated some of my node modules and it wasn't able to "gulp" after that.. Updated Owl Carousel 2 and now it works - except I had done some nice mods to the Owl Carousel which is now lost. (grr)
