I am getting the below error… during icinga2 agent installation… Can someone give an advice?  
Here, the output

Can you please advise on the below error

Fatal: Exception calling “generateIcingaConfiguration” with “0” argument(s): “Exception calling “checkConfigInputParamet  
ersAndThrowException” with “0” argument(s): “Argument -AgentName required for config generation.””

I got sometimes the same error but was too lazy to identify the root cause. Therefore, I just purged the agent and deleted the according host entry at the director and re-run icinga2-powershell-module.
