unfortunately I am new to Gulp, and I really need it to debug and sourcemapping, so to better understand less too, which is also quite new for me.

Anyway everything in place, I deploy trough usual bin/magento since the gulp exec and gulp deploy give me errors.

but it seems that gulp less --theme --map does not produce any less or map file, where they should be? If I use web inspector on Safari 11 it still give me the style-l.css and style-m.css and not the less behind them,

I read on another tread to cmd-click should bring me to the less, but it doesn't

what am I do it wrong?
