logical replication worker can't find postgis function

Hi!

I'm using logical replication on postgresql 13. On the subscriber, there's
a trigger on a table that calculates the area of the geometry that's in
another column.
I enabled the trigger with
ALTER TABLE atable ENABLE ALWAYS TRIGGER atrigger;

But the logical replication worker can't find st_area:

replication worker" (PID 1932237) exited with exit code 1

The trigger works well when I fire it in a normal update query.
How can this happen and how can I resolve this?
