Do-it-yourself PowerShell deployment fails right at the start

[matthewjlevy]

Hi all, I am trying to test deploying ESLZ using the "Do-it-yourself" AZ PowerShell commands. I have populated the variables as instructed, but the first commandlet (New-AzManagementGroupDeployment) doesn't support the parameter "topLevelManagementGroupPrefix". Is there something I am missing? Perhaps AZ PowerShell module outdated or something?

New-AzManagementGroupDeployment -Name $DeploymentName -ManagementGroupId $TenantRootGroupId
-Location $Location -TemplateFile .\eslzArm\managementGroupTemplates\mgmtGroupStructure\mgmtGroups.json
-topLevelManagementGroupPrefix $ESLZPrefix `
-Verbose
New-AzManagementGroupDeployment : A parameter cannot be found that matches parameter name 'topLevelManagementGroupPrefix'.
At line:5 char:33

• ... -topLevelManagementGroupPrefix $ESLZPr ...

•                                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  

  • CategoryInfo : InvalidArgument: (:) [New-AzManagementGroupDeployment], ParameterBindingException
  • FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.Azure.Commands.ResourceManager.Cmdlets.Implementation.NewAzureManagementGroupDeploymentCmdlet

I am using VSCode and the following versions of PowerShell and Az respectively:

Looks like you are missing a backtick on the first and second lines?

Try:

New-AzManagementGroupDeployment -Name $DeploymentName -ManagementGroupId $TenantRootGroupId `
-Location $Location -TemplateFile .\eslzArm\managementGroupTemplates\mgmtGroupStructure\mgmtGroups.json `
-topLevelManagementGroupPrefix $ESLZPrefix `
-Verbose

Could you also try updating the Az PowerShell module to the latest and then re-launch the PowerShell session. The command to update is:

Update-Module -Name 'Az' -Force

Thanks @jtracey93 for the response. The missing backticks in lines 1 and 2 are because I was struggling with the github markdown (ctrl+e) so may have manually removed them before my post, but I copied the snippet verbatim from the Readme.md

As for the Module version, I have run Update-Module -Name 'Az' -Force
and it ran without errors, but I still seem to have Az.resources v2.0.1

I am now trying to get PowerShell v7 installed and then configure VSCode to use v7 as the integrated shell. Fun and games.

Keep us posted. You generally need to close/terminate the powershell sessions before the upgrade shows as effective. But PowerShell 7 is a good idea anyway.

Keep us posted

Updated to PowerShell v7 restarted VSCode, Then updated the AZ module, restarted VSCode and now the commandlet is working:

New-AzManagementGroupDeployment -Name $DeploymentName `

                            -ManagementGroupId $TenantRootGroupId `
                            -Location $Location `
                            -TemplateFile .\eslzArm\managementGroupTemplates\mgmtGroupStructure\mgmtGroups.json `
                            -topLevelManagementGroupPrefix $ESLZPrefix `
                            -Verbose

VERBOSE:
VERBOSE: 16:27:13 - Template is valid.

Awesome thanks for letting us know
