Using Win10, and I run `yarn run build` under the /pro/jrs-ui-pro folder, I get the following error: [webpack-cli] Invalid value '${NODE_ENV:-production}' for the '--mode' option [webpack-cli] Expected: 'development | production | none' I attempted to run the following command to set the NODE_ENV value: set NODE_ENV=production But nothing seems to work. Any help is appreciated.
