Unable to Configure vCenter in vRealize Orchestrator 7.1

Hi,

I am trying to configure vCenter in VRO 7.1.0.4262825 version but its failing with some certificate error.

Error in (Workflow:Import a certificate from URL with certificate alias / Validate (item1)#12758) TypeError: Cannot find function getCertificateAuthorities in object DynamicWrapper (Instance) : [_Config]-[class com.vmware.o11n.plugins.configurator.model.PluginInventory] -- VALUE : com.vmware.o11n.plugins.configurator.model.PluginInventory@80dbcf25.

Tried to add vCenter 5.1, vCenter 5.5,vCenter 6.0. But faced same issue.

Attached logs and screen shot.

 Please let me know if there is a way to resolve this problem.
