@drupol Thank you for the patch in comment #6! The patch fixed the issue for me.
I'm encountering a similar issue. The view functions correctly when AJAX is enabled, but when submitting an exposed filter with AJAX disabled, the form redirects to an incorrect path.
The affected view is a page display that uses a contextual argument, and the exposed filters are placed in a block using the Better Exposed Filters (BEF) module, using datasources from a Search API index.
By modifying the form's action attribute using hook_form_alter(), I was able to redirect to the correct path (Thank you Ishani). However, I see this as more of a temporary workaround, it can become quite cumbersome if it needs to be applied across multiple views.
Drupal Core: 10.4.5
BEF: 7.0.5
Having the same issue. I've rerolled the patch.
