Logical replication stuck and no data being copied

I'm connecting from an aurora postgresql 12.4 instance to a postgresql 12.6
community edition.
The postgresql 12.6 is the publisher and the aurora db is the subscriber.
Most of the subscriptions and publishing worked.

Except for one table, which I've created a separate publication for.

One table is stuck and not copying data

I checked with the following query.

WITH active_pub_sub AS
(
select relname from pg_stat_all_tables a
join pg_subscription_rel sr on sr.srrelid = a.relid
where srsubstate!='r'
)
select relname as table_name,
pg_size_pretty(pg_total_relation_size(relid)) as total_size,
pg_size_pretty(pg_relation_size(relid)) as table_size,
pg_size_pretty(pg_total_relation_size(relid) -
pg_relation_size(relid)) as index_size
from pg_catalog.pg_statio_user_tables where relname IN (SELECT * FROM
active_pub_sub)
order by pg_relation_size(relid) desc;
table_name | total_size | table_size | index_size
-----------------+------------+------------+------------
translationitem | 16 kB | 0 bytes | 16 kB

This is what i see from the logs

I have tried:
ALTER SUBSCRIPTION sub_prodza_translationitem REFRESH PUBLICATION WITH
(COPY_DATA);
alter subscription sub_prodza_translationitem REFRESH PUBLICATION;

On the publisher.
# select * from pg_stat_activity where application_name

I'm not certain why the snapshot and replication is not working. I'm
guessing the the snapshot of the table completed but the wal process is
stuck.
