To resolve this issue, consider adjusting your PostCSS setup to eliminate the original mappings for specific imports. Instead of using empty or null values in the object for original mapping, explicitly define it as null.

Follow these steps to update your PostCSS configuration and address the problem:

// postcss.config.js

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
    // Integrate a custom PostCSS plugin to handle issues related to original mappings
    'resolve-postcss-source-mapping': function(css) {
      css.walkAtRules('import', rule => {
        if (rule.params.includes('@material')) {
          rule.params = rule.params.replace(/(original\s*:\s*\{[^{}]*?\})/g, 'null');
        }
      });
    }
  }
};
