"Register-AzAutomationScheduledRunbook" giving an error at Powers-shell script

Question

Hi All,

I am new to power-shell and cmldt.

I hv a power-shell script(.ps1) like "Invoke-xxDevopDt" and it registered as azure Runbooks with an azure Automation Account. This Runbook scheduled to do a another work on other date . Now ,I want to register this Runbook by using " Register-AzAutomationScheduledRunbook" at below ps-script as below

*param ( 
    [Parameter(Mandatory = $false)]
    [string]$resourceGroup='rsgrp_test',

    [Parameter(Mandatory = $false)]
    [string]$automationAccountName='Azureaucnt-test',

    [Parameter(Mandatory = $false)]
    [datetime]$startDateTime='01/05/2021 6:00:00 PM' ,

    [Parameter(Mandatory = $false)]
    [string]$vmResourceIds='/subscriptions/5454-7d8e-xxx-b628-yy3232/resourceGroups/TSTDEV/providers/Microsoft.Compute/virtualMachines/TSTDevVM',

    [Parameter(Mandatory = $false)]
    [String] $IncludedKBs='4588962',

    [Parameter(Mandatory = $false)]
    [datetime] $vmRestartDateTime='01/06/2021 4:00:00 PM',

    [Parameter(Mandatory = $false)]
    [String] $description = "Automated trigger from C# Program"

)
    #do Login-AzAccount  to login azure subcription  
    ....    
    #setting data for   
    $AddMinutes = 7

    # creating an scheduling and registering 
    $scheduleName = "testAPP_devopsSchedule_" + "$(Get-Date $vmRestartDateTime -UFormat %Y-%m-%d_%A_%H-%M)"
    $devopsSchedule = New-AzAutomationSchedule -ResourceGroupName $resourceGroup `
                                                      -AutomationAccountName $automationAccountName `
                                                      -Name $scheduleName `
                                                      -StartTime ($vmRestartDateTime.AddMinutes($AddMinutes)) `
                                                      -Onetime -Verbose

    #Createing a param for registering another PS-script as runBook with automation-acnt
    $params = @{"serverList"=$vmResourceIds;"testMessage"="test";"description"="Invoking Automation from Automation Account"}
    #register 'Invoke-xxDevopDt' is like a ps-script at runBook of automation-acnt
    Register-AzAutomationScheduledRunbook –AutomationAccountName $automationAccountName `
                        –Name 'Invoke-xxDevopDt' –ScheduleName $devopsSchedule.Name –Parameters $params `
                        -ResourceGroupName $resourceGroup*

But, it gave an ERROR at "Register-AzAutomationScheduledRunbook : A positional parameter cannot be found that accepts argument 'Invoke-xxDevopDt'."

Any help

Thanks,

Hi,

I tested the cmdlet and it worked for me, so I don't think it's a powershell issue. Try opening the script file in a hex editor and check if there are any non-printing characters such as zero width space in the command Register-AzAutomationScheduledRunbook.
