Fix WebpackInvocationError
in Webpack
✅ Solution
The "WebpackInvocationError", often featuring "Cannot read properties of undefined (reading 'tap')", typically arises from outdated or incompatible versions of webpack plugins or their dependencies. Ensure all webpack-related packages (webpack, webpack-cli, and all plugins) in your `package.json` are compatible and updated to their latest stable versions by running `npm install` or `yarn install` to regenerate your `node_modules` folder. If version conflicts persist, explicitly define compatible versions in your `package.json`.
