Dependent classes not working. CMDB Instance API; POST https://.service-now.com/api/now/cmdb/instance/ Create a record with associated relations;

[pFog]

The CMDB Instance API POST https://.service-now.com/api/now/cmdb/instance/ Create a record with associated relation endpoint works for classes that have no dependency. However I get this error when the class has a dependency and I can not figure out how to represent the dependency in the payload.

Endpoint:
/api/now/cmdb/instance/cmdb_ci_db_mssql_instance

Payload:
{
"outbound_relations":[],
"attributes":{
"name":"CI Test1",
"short_description":"The CMDB Instance API test of endpoint, Create a record with associated relations."
},
"source":"ServiceNow",
"inbound_relations":[]
}

Response:
{"result":{"items":[{"className":"cmdb_ci_db_mssql_instance","sysId":"Unknown","identifierEntrySysId":"Unknown","errors":[{"error":"MISSING_DEPENDENCY","message":"In payload no relations defined for dependent class [cmdb_ci_db_mssql_instance] that matches any containment/hosting rules: [cmdb_ci_appl >> Runs on >> cmdb_ci_hardware].

For inbound/outbound relations I have tried combinations of
target:
type:

I do NOT know how to represent the missing dependency mentioned in the error response.

The accepted solution in this post worked for me (add "depends_on" to the "inbound_relations")
