Hamburger manu on the app bar doesn't look right

[7seven7lst]

this is what i have for the package.json config:

"reactToolbox": {
    "include": [
      "APP_BAR",
      "AUTOCOMPLETE",
      "AVATAR",
      "BUTTON",
      "CARD",
      "CHECKBOX",
      "CHIP",
      "DATE_PICKER",
      "DIALOG",
      "DRAWER",
      "DROPDOWN",
      "INPUT",
      "LAYOUT",
      "LINK",
      "LIST",
      "MENU",
      "NAVIGATION",
      "OVERLAY",
      "PROGRESS_BAR",
      "RADIO",
      "RIPPLE",
      "SLIDER",
      "SNACKBAR",
      "SWITCH",
      "TABLE",
      "TABS",
      "TIME_PICKER",
      "TOOLTIP"
    ],
    "customProperties": {
      "animation-duration": "0.3s",
      "color-accent": "var(--palette-pink-a200)",
      "color-accent-dark": "var(--palette-pink-700)",
      "color-primary-contrast": "var(--color-dark-contrast)",
      "color-accent-contrast": "var(--color-dark-contrast)",
      "preferred-font": "'Jura', sans-serif;"
    },
    "output": "src/assets/react-toolbox"
  }

I cannot add "FONT_ICON" to that long list ( throw this Path must be a string. Received undefined error)

and the hamburger manu looks like this:

@7seven7lst It looks like you aren't including the Material Design Icons. See the "Roboto Font and Material Design Icons" here:
