If you want to do an unsigned image upload from Google Sheets to Cloudinary, here's the correct Apps Script snippet that does that:

function uploadImageToCloudinary() {
  var formData = {
    file: "<file_path>", // Replace with the file URL or base64 string
    upload_preset: "<upload_preset>" // Replace with your upload preset
  };

  var options = {
    method: "post",
    payload: formData
  };

  var response = UrlFetchApp.fetch(
    "https://api.cloudinary.com/v1_1/<cloud_name>/image/upload/",
    options
  );

  Logger.log(response.getContentText()); // Logs the Cloudinary response
}

I have used this on the Multi-AI Script product that I have. Earlier, I was using the default unsigned upload script and it wasn't working properly as it should, but now it's seamless.
