Can not get complex relations from api call

Question

Dear Data Citizens,

I have the following problem. I’m trying to get all complex relations from the Java Core Api. I tried to use the complexRelationApi.findComplexRelationIdsWithTargetAsset(UUID asset, UUID legType, UUID complexRelationType) method but it doesn’t work.
I double checked everything, I’m using the correct assetId, legTypeId and complexRelationTypeId but I get 0 return values (checked it with the size method). I also do not get any errors when using the workflow. And ofcourse I also have a complex relation with the given asset (the restAPI can find it).
Does somebody have an idea what I’m doing wrong?
Sincerley,
Stefan

The documentation is incorrect. Instead of the leg type ID, you should pass the relation type ID of that leg type.

So, instead of passing 1af54725-2751-40d9-b7d3-6fc38e7d1f57, try passing e2b405e3-8480-42d6-a50b-c7c360375821 instead.

complexRelationApi.findComplexRelationIdsWithTargetAsset(
    //target asset ID
	string2Uuid("a2c22995-a0fb-4816-b526-1ce8b05aa078"),
    //Relation Type ID (not leg type ID as mentioned by the doc)
	string2Uuid("e2b405e3-8480-42d6-a50b-c7c360375821"), 
    //Complex Relation Type ID
	string2Uuid("60740388-f8f2-4c17-b99f-e8bddad5e1e8")
	)

Never tried with the findComplexRelationIdsWithTargetAsset method, but here’s one that works. def alreadyMappedValues = complexRelationApi.findComplexRelations( FindComplexRelationsRequest.builder() .assetId(item.id) .typeId(codeMappingComplexRelationTypeUuid) .build() ).results
