The configuration object is invalid. Angular has initialized Webpack using a configuration object that does not align with the API schema

When attempting to run the angular application with "ng serve -o", I encountered an error message stating "Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema."

Prior to this issue, "ng serve -o" was functioning correctly. However, after installing "npm install ngx-bootstrap --save", "ng add ngx-bootstrap --component datepicker", and "npm install webpack --save-dev", the command "ng serve -o" is no longer working.

Below are the screenshots of the error: https://i.sstatic.net/4CV45.jpg https://i.sstatic.net/829ed.png

If anyone can assist me in resolving this issue, I would greatly appreciate it!

Thank you in advance for your help!

Answer №1

If you encountered an error, it may have been caused by the installation of Webpack:

npm install webpack --save-dev

The Angular CLI comes with its own built-in Webpack dependency to facilitate app building and serving. Adding an additional instance of Webpack to your project can potentially interfere with the pre-configured settings in the CLI.

To troubleshoot, try uninstalling Webpack and then attempt to serve the app once more.

npm uninstall webpack

ng serve -o
