ValidationError: Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema.

When i run this example i get error:
`ValidationError: Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema.`
How can i resolve it?

Start by reproducing the error when running the example and capture the complete webpack validation output. Inspect the example's webpack configuration and compare it with the Webpack API schema for the installed version. Done means the example starts without the configuration validation error.
