How is this possible "publication does not exist"

[Dave Cramer]

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
