Getting warnings for `export 'default' (imported as 'mod') was not found`

[amir20]

• Operating System: Mac Os 10.15.x
• Node Version: 14.13.1
• NPM Version: yarn 1.22.5
• webpack Version: weback 5.1.2
• mini-css-extract-plugin Version: 1.0.0

I am seeing multiple warnings that look like

WARNING in ./assets/App.vue?vue&type=style&index=0&id=5bcdaf03&scoped=true&lang=scss& 1:472-475
export 'default' (imported as 'mod') was not found in '-!../node_modules/mini-css-extract-plugin/dist/loader.js??clonedRuleSet-1[0].rules[0].use[0]!../node_modules/css-loader/dist/cjs.js!../node_modules/vue-loader/lib/loaders/stylePostLoader.js!../node_modules/postcss-loader/src/index.js??clonedRuleSet-1[0].rules[0].use[2]!../node_modules/sass-loader/dist/cjs.js!../node_modules/vue-loader/lib/index.js??vue-loader-options!./App.vue?vue&type=style&index=0&id=5bcdaf03&scoped=true&lang=scss&' (possible exports: )

Please open an issue in vue plugin, you should not use default import if you don't have locals

[amir20]

I can do that. But the stacktrace suggests the problem is with this plugin. Did I miss something?

Here ?vue, it is syntax for vue loader
