From the case:
Most Probable Cause:
This is a known issue from PRB1707022.
Solution Proposed:
There is a missing dependency requirement for plugin "CMDB CI Class Models 1.52" to plugin "Network Inventory Core Version1.4.2"
CMDB CI Class Models 1.52 Adds table cmdb_ci_network_topology with invalid identifier to tni_entity
From the PRB, you can attempt the following workaround:
To fix it in any instance that already has the problem, please go to the cmdb_related_entry table and delete the record with the sys_id 73b8c48e8d707110f8778302d753bcd2, which is the one presenting the issue for network topology.
This seemed to have fixed it for us. Hope it helps others.
