Error: The options object provided for Dev Middleware initialization does not adhere to the API schema and is considered invalid

Currently delving into the world of React JS, I am still a newcomer when it comes to these technologies.

Upon updating webpack from version 4.30.0 to 5.10.0 and running npm start, some errors surfaced. Despite attempting to remove the node_modules directory and reinstalling it before restarting with npm start, no changes were seen.

List of Dependencies :

"webpack": "^5.10.0",
"webpack-cli": "^4.2.0",
"webpack-dev-middleware": "4.0.2",
"webpack-hot-middleware": "2.25.0",
"webpack-pwa-manifest": "4.3.0",

Error :

javascriptwebpackwebpack-dev-middleware

Answer №1

Resolved a comparable problem by updating

    "webpack-dev-server": "^4.0.0-beta.3",

I suspect that version 3.x lacks full compatibility.
