As you can see I've created two project, one with nx9 and the other with nx10.
if you run yarn start:9
inside the nx9test folder the application will start correctly.
Instead if you run yarn start:10
an error during the build process will be showed.
This error is related tho the impossibility of scss-loader to find the correct path of the font asset. In particular Can't resolve './css/assets/font/fontello.eot'
. As you can see the path is incorrect and this is maybe related to this file https://github.com/nrwl/nx/blob/10.0.x/packages/web/src/utils/third-party/cli-files/models/webpack-configs/styles.ts, this commit https://github.com/nrwl/nx/commit/5b6df63.
