RHV Virtual Machines Discovery Pattern fails on Discovery - MULTIPLE_DEPENDENCIES error - when running schedule with multiple LDCsDescriptionWhen having a schedule with multiple LDCs, below step is creating relation from one cluster to all LDCs:35. Failover Create Relations Between Clusters and LDCas a result IRE throws: MULTIPLE_DEPENDENCIES.Steps to Reproduce > Create a RHV schedule with multiple LDCs to discover> Run the schedule> From Discovery Pattern Log > Open "RHV Virtual Machines" pattern log, see the pattern has failed.From the pattern log, we can see in step 35. Failover Create Relations Between Clusters and LDC, it has created relation to multiple LDCs.Open the discovery status from the schedule, check ecc input for "RHV Virtual Machines" pattern, if we run the input in IRE Simulation, we will receive error:1 : 16-07-2021 11:15:12 : Error : identification_engine : MULTIPLE_DEPENDENCIES Found multiple dependent relation items [{"parent":2,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] and [{"parent":1,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] in payload2 : 16-07-2021 11:15:12 : Error : identification_engine : MULTIPLE_DEPENDENCIES Found multiple dependent relation items [{"parent":3,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] and [{"parent":1,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] in payload3 : 16-07-2021 11:15:12 : Error : identification_engine : MULTIPLE_DEPENDENCIES Found multiple dependent relation items [{"parent":4,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] and [{"parent":1,"child":5,"type":"Contains::Contained by","sys_rel_source_info":{"source_feed":"UNKNOWN","source_name":"ServiceNow"}}] in payloadWorkaround**Issue1: IRE throws: MULTIPLE_DEPENDENCIES.** - PRB1517100 - new PRB Resolution:The step "35. Failover Create Relations Between Clusters and LDC" is not needed disabled discovery worked fine. **Issue 2: IRE error: MISSING_MATCHING_ATTRIBUTES** - PRB1499403 - resolved in Discovery and Service mapping Patterns plugin release 1.0.81 Resolution:Added null check in step 19 against "$cmdb_ci_rhv_server[].object_id"Related Problem: PRB1517100
