Forms Less File Parsing Error: Unrecognized Input

This error message indicates a problem in the forms.less file where an unrecognized input was encountered. This could be due to a syntax or spelling error.

To troubleshoot this issue, you can check the second line of forms.less for any syntax or spelling errors, especially the format of the last input item.

You can also try updating your CSS or LESS parser to ensure you are using a version compatible with your project.

If these solutions do not work, you may need to check your project's dependencies and configurations to ensure they are correctly installed and configured, and compatible with other parts of your project.
