Error: type 'Null' is not a subtype of type 'String' when calling getEntityRelationService().findInfoByQuery #27

Open maksonlee opened 6 months ago

Environment

Description Got exception when tried to call getEntityRelationService().findInfoByQuery, the root cause is that 'fromName' of response is null, the same query can be executed fine with REST API.

    RelationsSearchParameters parameters = RelationsSearchParameters(rootId: 'bcbca450-c1a8-11ee-9f93-492ffd078c6c', rootType: EntityType.ASSET);
    RelationEntityTypeFilter filter = RelationEntityTypeFilter('Contains', [EntityType.DEVICE]);
    EntityRelationsQuery query = EntityRelationsQuery(parameters: parameters, filters: [filter]);
    List<EntityRelation> relations = await relationService.findInfoByQuery(query);
