Can't find out what is caussing this file to fail migration to tailwind 4.x

[lveillard]

I removed the function and still it fails to be transformed. I don't find a way to run the migration tool in verbose mode so it explains to me what is failing. Any ideas on how to transform it?

const withOpacity = (variableName) => {
  return ({ opacityValue }) => {
    if (opacityValue !== undefined) {
      return `rgba(var(${variableName}), ${opacityValue})`;
    }
    return `rgb(var(${variableName}))`;
  };
};

You may need to remove safelist, media and convert the withOpacity() return value to a string.
