Facets stopped working after update to Drupal 10

Found the culprit: it was some custom code implementing a search api subscriber and requiring a small code change in order to work with Symfony 6.

Before:

$query = \Drupal::request()->query;
$f = (array) $query->get('f');

After:

$query = \Drupal::request()->query;
$f = $query->all()['f'] ?? [];

So it's not caused by Facets module, closing this issue.

Thank you for posting your solution, I had exactly the same problem and took me quite a while debugging :)

Thank you for your solution. It really helpful.

Whoever comes across this but does not use custom code - the issue in the facets module has been fixed here - https://www.drupal.org/project/facets/issues/3367124 🐛 Drupal 10: InputBag::get() may no longer return an array in Symfony 6 Fixed

Thanks for the solution @drubb. It works for me.

Thanks for this. Not an easy find :)

I'm really glad somebody posted this as an issue, because I ran into the same thing because of some custom code I didn't realise needed updating for Symfony 6. It's not really a deprecation so much as how you need to use the request object and its functions. Very hard to otherwise find an answer on.

@drubb Thank you for your solution. It was really helpful.
