Steps to reproduce

publicPath:
    process.env.NODE_ENV === 'production'
      ? 'http://localhost:8000/static/frontend'
      : '/static/frontend',

What is expected?

Script publicPath is the same and is correct

<script src="http://localhost:8000/static/frontend/js/safari-nomodule-fix.js" type="module"></script>

What is actually happening?

Script publicPath is wrong, 2nd slash after http is omitted

<script src="http:/localhost:8000/static/frontend/js/safari-nomodule-fix.js" type="module"></script>

Why? How to pass absolute url for production? (I have all static files hosted on CDN on another domain)

 configureWebpack: (config) => {
        const SafariNomoduleFixPlugin = config.plugins.find(
            (plugin) => plugin?.constructor?.name === 'SafariNomoduleFixPlugin'
        );
        if (SafariNomoduleFixPlugin) {
            SafariNomoduleFixPlugin.unsafeInline = true;
        }
}

In my project, I use https://github.com/vuejs/vue-cli/pull/7247 to solve this issue.
