Hi,

It seems that i have the same problem as this thread: https://github.com/react-toolbox/react-toolbox/issues/148

in ./ClientApp/app/components/app/app.component.scss
Module build failed: 
undefined
              ^

I just updated my npm package, Is there a solution to fix it?

Can you show the scss file where you define the theme? I was facing this issue because I was using wrong parameters for default, lighter and darker for some colors.

I was using:

$app-primary: mat-palette($mat-blue-grey, A700, A500, A900);

But if you go to the definition of $mat-blue-grey in _theme.scss of material, those variables are not defined, just a few have the ‘A’ before:

$mat-blue-grey: (
  50: #eceff1,
  100: #cfd8dc,
  200: #b0bec5,
  300: #90a4ae,
  400: #78909c,
  500: #607d8b,
  600: #546e7a,
  700: #455a64,
  800: #37474f,
  900: #263238,
  A100: #cfd8dc,
  A200: #b0bec5,
  A400: #78909c,
  A700: #455a64,
  contrast: (
    50: $black-87-opacity,
    100: $black-87-opacity,
    200: $black-87-opacity,
    300: $black-87-opacity,
    400: white,
    500: white,
    600: $white-87-opacity,
    700: $white-87-opacity,
    800: $white-87-opacity,
    900: $white-87-opacity,
    A100: $black-87-opacity,
    A200: $black-87-opacity,
    A400: white,
    A700: $white-87-opacity,
  )
);

Using only the numbers and removing the ‘A’ before, fixed the issue for me.

$app-primary: mat-palette($mat-blue-grey, 700, 500, 900);
