Hi Éric,
A 404 error is the correct response for that URL because there is not a page found at that URL. It is a REST API endpoint that it is only accessed via a REST API request made internally from your own website. Google is finding the URL in the Javascript snippet and choosing to crawl it, but there are not any links to this page anywhere on the site. They probably shouldn’t be reporting it like it’s an issue when they’re basically taking a guess on that URL in the first place.
I would mark the issue as fixed in GSC to resolve the error message in their dashboard.
Okay, I’ll do that. We’ll see how the GSC behaves.
Thanks for the feedback. Sorry, I made you answer twice.
Thanks for your plugin.
Éric
