java.lang.NullPointerException: Host management IP should not be blank
        
Stretch cluster workflow is failing in task CreateAZ2EsxiInventoryAction while making POST call for new hosts provided in the spec.
Out of the 2 Management traffic networks- Host Management and  VxRail Host discovery, host management network does not start with "Management Network-".

Cause

Environment has MANAGEMENT transport type network portgroup name which is not satisfying prefix match condition to start with either “Management Network_” or "Management Network-". As prefix is not matched so it's not assigning Management IP and as a result of that workflow is failing in later action while updating the inventory.

Resolution

VCF 4.x does not support changing the management portgroup name. The name should be reverted back to the original ensuring to has the correct prefix.
