Add orchestrator server with multi-node plug-in error - java.lang.NullPointerException

[holashh]

Hi all,

I have fresh installation of vRO 6.0.2 for testing purposes.

I have to test all our features and one of these is interconnection with multi-node plug-in.

My case is: I have one instance of vCO in version 5.1 and multi-node plug-in in version 72 (the latest one for this build) and trying to connect to my new vRO 6.0.2 (with build-in multi-node plug-in).

I am able to connect server and I see him in inventory, but when I try to generate a proxy workflows, I got the error

java.lang.NullPointerException (Workflow:Add an Orchestrator server / Add host (item0)#14)

Here is server.log output:

Should this be caused by missing firewall rules?

Thanks,

Jan

Most likely it is the version of the plugin vs the version of target vRO instance.

It will work if both vRO versiona are same 6.x and latest multi node plugin is used

It should work if one vRO  is 5.5.x ant the other is 6.x (did not test it) and you use latest avaialbe Multi node plugin

Quite sure it won't work in case of 5.1 -> 6.x (Certain pluign funcitonality like generation of workflows uses same API as vRO Workflow Designer which got changed between versions. Meaning that if you are not able to conect vRO Server 6.0.x with vRO client 5.1 plugin also wil lnot be able to work.
