Cause
Based on the error, when IRE queries cmdb_ci_dns_name table, it gets "null" result.
This is likely caused by a query business rule on cmdb_ci_dns_name table.
The business rule might have filtered out some CIs which IRE is trying to access.
Resolution
Either disable the query business rule, or use "Identification Inclusion Rule" to filter out the CIs that the query business rule blocks.
