Looks like the image coming from the API is just a URL and not an Image data type as Bubble would interpret it…you can fix this easily by not using the Image data type as the field in the database and instead just use a text type to save only the URL…of course that will restrict some functionality a bit compared to working with a real ‘image’ type, but you could still use the URL alone as text to display an image via an image element.
An alternative, is to attempt on the API call to make the MediaURL be of type Image.
