To address the Bootstrap warning related to the abs() function, you can update Bootstrap to version 5.3.2 using either npm or yarn. Here are the commands to update Bootstrap:

Using npm:
npm install bootstrap@5.3.2

Using yarn:
yarn add bootstrap@5.3.2

This fix also will be included soon.

Thanks

Thank you Faizal. It worked this time. I removed the draggable folder and tried again. Below is the output. Appreciate your help.

This error can sometimes be caused by third-party plugin updates or changes in the configuration.

If you are not using the draggable plugin in your project, you can temporarily remove the `draggable` folder from your project as a workaround. This may resolve the issue until a more permanent solution is available.

Remove the `/tools/webpack/plugins/custom/draggable` folder from your project.

If the issue persists, you can try replacing your `/tools/webpack.config.js` file with an updated configuration file. You can find an example of an updated configuration file in this
https://gist.github.com/faizalmy/07c1ca0caa544e37735e2404e963c8f4

Download the updated webpack configuration file and replace your existing `/tools/webpack.config.js` file with it. Be sure to backup your existing configuration file before making any changes.

We greatly appreciate your patience and understanding.

Thank you for the response. I did what you mentioned. It ran this time. Below is the output I got.

I appologise for the inconvenience. This issue is specifically on Windows.

As workaround, you can try replacing some lines in the /tools/webpack.config.js file with the workaround code provided in this link [https://gist.github.com/KeenthemesHub/2189b96490016bc32f88b3091e446906#file-webpack-config-js-L113-L116]. This should help in resolving the configuration error.

If you continue to experience any difficulties or have further questions, please don't hesitate to reach out. Thank you for your patience, and we appreciate your understanding.
