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 'disableHostCheck'

Hi,
I just created a vue-single-spa app.
I have a root folder where I created a 'root-config' app (via CLI selecting the root-config option) and a 'vue' app (via CLI)

After the setup, like suggested by the CLI, i ran npm run serve, which gave me this error:

INFO  Starting development server...
 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 'disableHostCheck'. These properties are valid:

I think it's related to Webpack. How can I fix it?

This will be resolved when single-spa/vue-cli-plugin-single-spa#44 is merged.
