Hi @jason1

Would you be able to send over the project?

The pop error message points more on the JS than CSS. It would be unusual to see this in the CSS file, but the file you’ve pointed out is already after running build, so we should also check if the error is also thrown for the pre-build version when you run the server.

This is the main code. The error only happens when running ‘webpack --config webpack.prod.js’
