Description

Since #42195 the UI of logs changed between the profiler and the exception page so createFilters was removed from base_js.html.twig’s Sfjs.

exception.js also defines its own Sfjs with a createFilters method it calls on DOMContentLoaded.

Problem is, base_js.html.twig’s Sfjs overrides exception.js’ one because the latter does not define loadToolbar.

As a result, when DOMContentLoaded kicks in, Sfjs.createFilters is called while it does not exist anymore so an error is logged and filters don’t work.

Uncaught TypeError: Sfjs.createFilters is not a function

Else, the UI would look like this on exception pages:

How to reproduce

Display the ErrorHandler’s exception page with some logs and the profiler’s toolbar enabled.

Possible Solution

Not sure about this. The fact the web profiler and error handler can override each other’s Sfjs seems weird.

Also, remnants of Sfjs.createFilters are still present in translation.html.twig.
