API InvokeElem fails after upgrading OCUM 7.1 to 7.3 [Resolved]

[POLICARD]

I'm using NetApp Manageability SDK 5.4P1 with Powershell for connecting to an OCUM server in version 7.1

There is a very simple Powershell script I am using to gather information using API to connect OCUM:

We have upgraded OCUM 7.1 to OCUM 7.3

Since this upgrade the same script is going wrong :

The strange here is Zedi is able to connect and to get a result for the same Element "cluster-iter" with same credentials and Port ...

Do anyone has an explanation ?

In fact DSK 9.3 was not properly loaded during my last tests.

It's working fine now ... 😐
