It helps with the ERRORs you get (e.g.
worker process: logical replication worker for subscription 33650 sync 20258 (PID 32898) exited with exit code 1
or
worker process: logical replication worker for subscription 185231525 (PID 78166) exited with exit code 1

Now on the publisher side what does :
select * from pg_stat_replication ;
tell you?
