“paletteProvider -> e” sounds like a typical javascript uglification/minification problem.
You have a class named something, and try to inject it, and this works fine when running ‘serve’, which does not minify. When you run build, the minification strips the classname and injection fails.
One solution is to drop minification during build, another is to fix injection so that classnames aren’t required.
Does this happen in the base project as it is on Github, or did this problem come after you did some modifications? If I find some time, I will look into it.
