ValidationError: Invalid options object

[Ascyt]

When I try to run the server, I get an error:

ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
         - options has an unknown property 'overlay'. These properties are valid:
           object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?, host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocketServer? }

Here is my full output on my Windows 11 PC:

>npm run serve

> vue-bootstrap-boilerplate@2.2.0 serve
> vue-cli-service serve

Also it might be worth noting that I'm using Node.js v14.17.3, since I'm unable to install with a newer version, as seen in this issue: #9

I did manage to make it work my deleting the troublesome property out of the vue.config.js file:

    overlay: {
      warnings: true,
      errors: true
    }

Not sure exactly what the point of this property is. Might be worth taking a look at this, though.
