Hi @AP I've shared the solution over email, along with remix, you can try it, and followup on email if you feel stuck.
Also, sharing a part of it here - The issue is with the inputs, the image you are passing is nested inside objects and is not read in the API call body. Instead, use the file upload trigger to upload the picture as a multipart file and then pass it to your API Call node as body. From the file upload trigger, you'll get the buffer and path, which you can use.
