After minor upgrade from 7.0.3 to 7.0.4 zabbix started to produce this randomly generated error:

3836959:20240924:112709.954 [Z3005] query failed: [0] PGRES_FATAL_ERROR:ERROR:  null value in column "value" of relation "housekeeper" violates not-null constraint
DETAIL:  Failing row contains (717095, events, triggerid, null).
 [insert into housekeeper (housekeeperid,tablename,field,value) values (717095,'events','triggerid',null);
]

Note - minor automatic DB patching performed successfully.

2 of 2 LLD workers produce it. I may assume this happening the a LLD rule is deleting lost resources.

Filtered as "egrep "query failed" -A2 zabbix_server.log" is attached.
Note - some IDs are repeating multiple times, some do not.
