Webpack has been initialised using a configuration object that does not match the API schema whent running a React demo project

I am trying to run a react js project using node js. According to the tutorial it is using web pack server. But when I am starting the project it is giving the below error .

Webpack has been initialised using a configuration object that does not match the API schema whent running a React demo project

I have installed the web server package project inside the same directory where I have created the node project and inside package.json I have server configuration like this.

"scripts": { "start": "webpack-dev-server --hot" },
