php 8.1 fatal error

I am not able to reproduce this issue. Can you tell me how to reproduce this issue in a fresh installation?

Confirm, D9.5.9 php 8.1.17

"PHP Fatal error: ob_get_clean(): Cannot use output buffering in output buffering display handlers in /var/www/chel-dpsh.ru/data/www/-----/vendor/twig/twig/src/Template.php on line 399"

I get this error on the page created by the views module. I display teasers of materials on the page, in the template of which I actively use the capabilities of the Twig Tweak module. In my case, the problem was in this module. In the module file TwigTweakExtension.php there really is an ob_end_clean();

To solve the problem:

1. I applied a patch: https://gist.github.com/omahm/fadf6491c33487ddce54c43b9eb2c3a0#file-ob_g...
2. Also increased the memory_limit value in php.ini from 128 to 1024

Moving here, since it seems the problem seems to be with twig tweak and only triggered by fast permission administration (with a lot of modules).
See last comment, also seems to provide a solution in code.

ob_end_clean() is only used by PHP filter. Have you enabled this filter?

I have not installed https://www.drupal.org/project/php → . It is not even on the site.

Is it possible that any other module uses/brings a php filter?

I am D10.1

Twig Tweak does have PHP filter. But it needs to be enabled in your settings.php file.

Sorry, what do you mean?
I don't think I have ever enabled a php in settings.php

What is the line I should look for?

If you don't have PHP filter enabled then the error is unlikely related to Twig Tweak module.

I'll run Devel soon and provide more details.

Drupal 10.1.7 and PHP 8.1.24
The error seems to be triggered by the by fast permission administration with a lot of modules permissions. Disabling the module gets rid of the error, however I need the module enabled.
Unfortunately the patch from #6 didn't apply, although I don't see any conflicts. Anything else I could try?

Following up on #17. In my case, the issue seems more a memory issue than a Twig Tweak related issue. The issue occurs when working with limited memory and a lot of nester entity references.
