Problem faced while trying to run thebe locally

[Kandaraa]

Describe the bug

hello everyone

trying to run thebe locally I go this error: Error: Compiling RuleSet failed: Exclamation mark separated loader lists has been removed in favor of the 'use' property with arrays (at ruleSet[1].rules[2].loader: style-loader!css-loader)

when I run this command: yarn run build:watch

and this is the line I think that causing the issue in webpack.config.js : { test: /.css$/, loader: "style-loader!css-loader" },

thanks in advance
