Azure automation runbook Completed before running the code

Question

I have a situation where in the Azure automation runbook results in 'Completed' state and does not run the 'actual' code. I have pasted the code below. It creates a Event Hub inside a Namespace. The code works perfectly executing in local machine but it does not execute in Runbook.

I have written a 'write-output "Declaring local variables for use in script"' --> to check if the printing is working. However, the code is not going beyond that. I am sure, I am missing some thing. Kindly help me.

Param(
    [Parameter(Mandatory=$true)]
    [string] $NameSpaceNameName,

    [Parameter(Mandatory=$true)]
    [string[]] $EventhubNames,

    [string] $ProjectId,

    [int] $PartitionCount,

    [Parameter(Mandatory=$true)]

You have $NameSpaceNameName in the parameters section of the runbook but later in the runbook at 50th line you have $NameSpaceName which is not the same as mentioned in parameters section. Correct it and then it should work as expected. One suggestion is to always have an else block wherever you have if block to overcome such issues in future.
