relation "hdb_catalog.event_triggers" does not exist. null

[enes-get-local]

Hey all, our backend team have implemented our backend functions as working with hasura. We been using event triggers which proceed when happen any crud operation in responsible table. Everything was working perfectly until yesterday we faced an issue. Our sql statement return as undefined :

sql: SELECT name FROM hdb_catalog.event_triggers WHERE name = '${eventName}';

Then i tried to run this query in hasura dashboard and i get this error :
relation "hdb_catalog.event_triggers" does not exist.null

Can you please help with this, is there a version change of hasura ? Our codebase and database configuration never changed for long time and suddenly we got this error.
