How to Hide iControl Exception

I am working with a BIG-IP 10.2.4 Build 771.3 Engineering Hotfix HF6 utilizing Powershell and using iControlSnapInSetup_56.

My goal is to create a Powershell script, fed via a csv file with member relevant data, which allows to enable disable pool members, and that is working fine.

However the issue I have ran into is an exception thrown by iControl which I cannot hide no matter what I have attempted thus far. In the image below you can see the exact error:

I have attempted Try{}Catch{}, traps and even the ErrorAction settingsd to no avail; if the action attempted fails, the error will be printed to the Host no matter what. I know the IP address is wrong :), but the goal is to test things with possible errors, because users do provide bogus data or fat-finger data at times.

Thank you for your help and time.
