What causes the product.url error in Facebook dynamic ads setup?

Question

Facebook

Welcome all! I downloaded the data feed template for Facebook, inserted an example of products directly into it and inserted the correct link into the URl column, but this error pops up when editing the ad. I don't understand what's the matter.

Answer 1

It is clearly written in the message that the link should start with http or https , and you just have product.url .
Put the link in this format:
https://your_site/product.url
