vRealize Operation Manager 6.5 connectivity

Hi,

I have confirmed that vRealize Operations Manager 6.5 is compatible with Usage Meter 3.5.  I am trying to add any user to the Usage Meter, but am failing.

Adding the user as username@domain I receive the following

org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Unable to unmarshal (to type [simple type, class java.lang.String]): Could not map [NOT_EXISTING] to ResourceState (through reference chain: com.vmware.ops.api.model.resource.ResourceDtoList["resourceList"]->com.vmware.ops.api.model.resource.ResourceDto["resourceStatusStates"]->com.vmware.ops.api.model.resource.ResourceStatusState["resourceState"]); nested exception is org.codehaus.jackson.map.JsonMappingException: Unable to unmarshal (to type [simple type, class java.lang.String]): Could not map [NOT_EXISTING] to ResourceState (through reference chain: com.vmware.ops.api.model.resource.ResourceDtoList["resourceList"]->com.vmware.ops.api.model.resource.ResourceDto["resourceStatusStates"]->com.vmware.ops.api.model.resource.ResourceStatusState["resourceState"])

Adding the user as a local user of vROps or domain\username I receive the following:

com.vmware.ops.api.client.exceptions.AuthException: API call failed, reason = 401

I've tried different permission levels, but am not getting any improvement. 

I noticed that the vCenter references vROPs still as 6.4 and the Usage meter shows the below.  Is this contributing to the problem?

Thanks in advance,

Rob
