Field_filter hook not running?

Anki Add-ons
1

Hi all, I’ve been having an issue where, as far as I can tell, the field_filter hook is not running, even though the card_did_render and webview_will_set_content hooks at least are running. I feel like I’m missing something simple…

To reproduce:

OS: Ubuntu 20.04.5 LTS
python==3.9.10
Qt==6.3.1
PyQt==6.3.1
anki==2.1.54
aqt==2.1.54

This is the add-on I am using:

from anki import hooks
from aqt import gui_hooks


def f(*args):
    print("field_filter run")
    return ""


hooks.field_filter.append(f)
hooks.card_did_render.append(lambda *args: print("card_did_render run"))
gui_hooks.webview_will_set_content.append(
    lambda *args: print("webview_will_set_content run")
)

Here is the output on startup:

Anki starting...
Initial setup...
Running with temporary Qt5 compatibility shims.
Run with DISABLE_QT5_COMPAT=1 to confirm compatibility with Qt6.

And on reviewing a card:

webview_will_set_content run
webview_will_set_content run
webview_will_set_content run
webview_will_set_content run
card_did_render run

The field_filter hook doesn’t seem to run. Any help would be much appreciated. Thank you!

It only runs when there are custom filters in the template. If you put something like {{foo:Front}} in the front template for example, it will run.
