Thanks Mirko,
The image src will be unknown because the images were removed in the custom endpoint as per the code I provided. Simply accessing the “Edit” function of the product fixes the problem for that product. The question is “What is missing in my code that is not re-initializing the product. The new items display but the old links remain. Do you know how to delete those links to the old products in the code?
Thank you. That did the trick.
