vCO Multi-Node issue

Hi,

I have deployed two vCO appliances (5.5.2) - vco1 and vco2.

vco2 has the vCloud director plugin installed and has a connection established. I am able to successfully execute workflows (example workflow - Add a user in a vCloud Org).

On vco1, I have the multi-node plugin configured and have added vco2 as a remote vCO (as a part of Add a vCO workflow, it has generated proxy workflows). Now when I try to execute the "Add a User" vcloud workflow from vCO1, it generates an error like the below -

Expected 'vCloud:Organization' but got 'vCloud:application/vnd.VMware.vcloud.org xml' type.

While I run the workflow on vCO1, it asks for a vCloud org name for which I navigate to the remote vCO and then select the vCloud org, hope this is correct. Also, I don't see any trace of this workflow execution on the remote vCO (vco2)

Any ideas ?

Thanks,

Ravi
