Looking at the vSphere connection configuration via UI we can see that the value for VCenter cluster is populated with the "networks" value instead of the "computeCluster" one

From the form query it seems it is linked to the Network:
======================================
vCenterCluster = domain?.topology?.networks?.[0] || '';
======================================

Our understanding it that it should pickup the cluster name:
======================================
topology.computeCluster
======================================
