is there a way to find out why zapier upload to youtube shows succesful in zapier but ' video unavailable' in yo

I have a workflow to get a video and thumbnail from trello, and I wish to upload it to youtube, using the card title and description. I wish to use the thumbnail as well, but I figure I can update the thumbnail after I am able to upload the video.

There are no errors showing on the zapier front, and I am able to verify the video and thumbnail do exist via manual checking.

youtube gives a success response and gives a link to the video.

the video is not showing with a 'not available' error. I have tried multiple youtube accounts and checked any and all permissions I could find.

this is a recording of all the steps I've walked through :

this is the javascript code to seperate the video and thumbnail urls.

// Access the 'files' field from the inputData
const fileUrl = inputData['files'];  // The 'files' field contains the two URLs separated by a comma

// Log the input to verify the value of 'files'
console.log('Input file_url:', fileUrl);

// Check if fileUrl is defined and not empty
if (fileUrl && typeof fileUrl === 'string') {
  // Split the fileUrl string into an array based on the comma
  const urls = fileUrl.split(',');

  // Log the split results to see the URLs
  console.log('Split URLs:', urls);

  // Assume the first URL is the thumbnail, and the second URL is the video
  const thumbnailUrl = urls[0].trim();  // Thumbnail URL is the first item
  const videoUrl = urls[1] ? urls[1].trim() : '';  // Video URL is the second item, if present

  // Log the video and thumbnail URLs
  console.log('Thumbnail URL:', thumbnailUrl);
  console.log('Video URL:', videoUrl);

  // Output the result
  output = {
    video_url: videoUrl,
    thumbnail_url: thumbnailUrl
  };
} else {
  // If 'files' is undefined or empty, set output to empty values and log the error
  console.log('No valid file_url input found.');
  output = {
    video_url: '',
    thumbnail_url: ''
  };
}

Please feel free to ask any questions that may clarify the problem at hand.
