IMG not shown from an API POST

Hi.
I have set an API endpoint to send img.
I have text field for name and image field for image.
According to doc, we can Post to image field using an string with url. This is what I do. The thing is created, but the image doesn’t show. If I click “see” in DB, I can see the image in new tab. But not in DB itself and not on the preview app too.
The image come from a public url. I doesn’t see any option to “saved” to s3. I try to encode the url, but this doesn’t work too.

What can I do?

Anyone?

Fix it using the :saved to s3
