Uglify breaks npm run build, log report doesn't say anything particular, npm run dev works

Question

This is the error message npm run build produced:

ERROR in build.js from UglifyJs
Unexpected token: punc (() [src/App.vue:40,0][build.js:139,6]
npm ERR! code         


        

Answer 1

Not sure what was the issue but moving the project to a different directory solved it.
