Exactly this error has been fixed in https://www.espruino.com/ide/ for a while, but the changes may not have made it into the Chrome app yet.
i don't minify the code
I'd check your settings again. The code in the error message ..((Math.sin(p)+1)/2),p+=0.02;,50); has definitely been minified.
..((Math.sin(p)+1)/2),p+=0.02;,50);
If you turn off minification it'll work.
