How Fix "Invalid Host Header" Error In Vue.js 3 Project?

The "invalid host header" error in a Vue.js 3 project typically occurs when the host header sent by the client does not match the host header expected by the server. This can happen when you are trying to run the development server with a different host header configuration than what is specified in the Vue.js project settings.

To fix this error, you can try specifying the host header configuration in the Vue.js project settings to match the one you are using when running the development server. You can do this by adding a "devServer" configuration in your vue.config.js file, like so:

1
2
3
4
5

module.exports = {
  devServer: {
    disableHostCheck: true,
  }
}

Alternatively, you can try running the development server with the "--disable-host-check" flag to bypass the host header check. You can do this by appending the flag to the npm start command, like so:

1

npm start -- --disable-host-check

By following these steps, you should be able to fix the "invalid host header" error in your Vue.js 3 project and run the development server without any issues.
