How is this possible "publication does not exist"

The publication exists but for some reason the function can't find it

SELECT * FROM pg_logical_slot_get_binary_changes('debezium', NULL,
NULL,'proto_version','1','publication_names','dbz_publication');
ERROR: publication "dbz_publication" does not exist
CONTEXT: slot "debezium", output plugin "pgoutput", in the change
callback, associated LSN 0/307D8E8
postgres=# select * from pg_publication;
pubname | pubowner | puballtables | pubinsert | pubupdate |
pubdelete | pubtruncate
-----------------+----------+--------------+-----------+-----------+-----------+-------------
dbz_publication | 10 | t | t | t | t

(1 row)
