community,

i have a symfony project (3.1.10) and use ajax requests (jquery.ajax) to load data. If the request fails, the debugger toolbar shows the error but creates no profiler entry, there is only a n/a in the profile column. So i have no chance to get the reason for the failing. I remember in symfony 2.7 there was a profiler entry for failed ajax requests. Can someone help me?

debug toolbar

    I am pretty sure it's because you get a 500 and no 4xx error, this probably means that your php code exited with a fatal error, so no php script execution anymore, therefore no profile. Commented Feb 22, 2017 at 15:28
  • Thank you for your answer. But i remember that there was an profile entry for 500 errors. And this blog post there is it also: symfony.com/blog/… Commented Feb 23, 2017 at 12:54

    yes, but still - there are fatals errors with PHP which are so 'basic fatal' that no further PHP execution is possible (e.g. incorrect use statements and so on) - and you want get any further details in the profiler about them. visit your logs if there's any additional information, sometimes it is.

Make sure that the URL of your AJAX request actually uses the app_dev.php front controller. Otherwise no debug data is recorded for the profiler to display.

Seeing the same. But you know you always can open /_profiler/ page on your instance, find your ajax call and find out what happened.

The request also does not appear at the profiler page. Just like it was never executed.
