Safari shows a 404 error, but not the error path

Today while developing a web app, I noticed a 404 error in the console.


However, unlike most 404 console errors, it did not show the path to the resource (html file) it was trying to load. Typically, I use this info to instantly determine whether there is a typo in my code or if a resource was not uploaded, etc.


Is this by design? Am I missing something?
