Webpack MDB UI KIT PRO new theme

Hello,

I would like, with mdb-webpack-starter, to create a new custom theme (as shown here: https://mdbootstrap.com/docs/standard/content-styles/theme/).

Here is what I did and the result I get :

I started by cloning mdb-webpack-starter like this:

gh repo clone mdbootstrap/mdb-webpack-starter (GitHub CLI)

Then in "./mdb-webpack-starter" I did :

npm install

Then I installed the pro advanced version of mdb "mdb-ui-kit-pro-advanced" like this:

npm i git+https://oauth2:MY_ACCESS_TOKEN@git.mdbootstrap.com/mdb/standard/mdb-ui-kit-pro-advanced

Finally, in "./src/scss/index.scss" I copied the code from the documentation like this:

@import '~mdb-ui-kit/src/mdb/scss/mdb.pro.scss'; // I adapted documentation to my case.

[...]

// include theme styles
@include mdb-theme($my-theme);

I run the dev server with:

npm start

And I get the following errors:

ERROR in ./src/scss/index.scss
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleBuildError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):

Do you have an idea?

Thanks
