This is a maddening error.

To summarize:

• I created a workflow using Make, but encountered an error when uploading products (as shown in the image).
• 
• Initially, I suspected issues with the links or images, but manual tests via the admin panel with the same URL/images worked perfectly.
• The error only occurs when using the API endpoint for uploads.
• The customer support team couldn’t resolve it, and I’m now blocked from proceeding with my work.

Is anyone able to help? This is an earnest request for assistance.

"The error 'Could not generate an image extension name' is truly unexpected."

What does this "data" mean? What kind of data do I need? Can anyone tell me?
