【Vue】デプロイ時にjavascript_pack_tag 'application'の部分でMIME typeエラーになる

前提・実現したいこと

Vue.js（webpack）+Railsで作ったアプリをデブロイしたいですが、下記のエラーが出て画面が真っ白になります。
開発環境ではこれで動いていたのですが、デプロイしたらエラーとなりました。
パスがダメなのでしょうか。
アドバイスを頂けますと幸いです。

試したこと

type="text/javascript" を追加してみてもダメでしたので、パスがだめなのかと思っています。
application.html.erb

ruby
1    <%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload', type="text/javascript"  %>

補足情報（FW/ツールのバージョンなど）

Rails 6.0.3.4
Vue 2.6.2
"webpack-dev-server": "^3.11.1"

自己解決

お恥ずかしながら、webpackのビルドし忘れでした。
bin/webpackをしましたが、下記のエラーがでました

Module build failed (from ./node_modules/postcss-loader/dist/cjs.js):
ValidationError: Invalid options object. PostCSS Loader has been initialized using an options object that does not match the API schema.

postcss-loaderのバージョンは3.0.0にダウングレードすることで、bin/webpackが通りました。
