Argument `$map` of `map-get($map, $key)` must be a map

Just installing the library with yarn and loading it (SCSS) I get the following error:

`@import "~daemonite-material/assets/scss/material";`

no custom changes just loading i get this error:

`@return map-get(map-get($theme-colors, $key), light);
^
Argument `$map` of `map-get($map, $key)` must be a map
in _functions.scss (line 70, column 11)
`

Any idea why ??
