While there is no such issue with AAI in elalto, I observed the following isisue on master branch of onap:
With the AAI instance deployed by the latest oom, the query to "aai/v16/cloud-infrastructure/cloud-regions/cloud-region/WRCP1/RegionOne" returns correct content. However, the query to the sub object "aai/v16/cloud-infrastructure/cloud-regions/cloud-region/WRCP1/RegionOne/esr-system-info-list" returns wrong content (content of the relationship object).
