Get-AzureRmResource : A parameter cannot be found that matches parameter name 'Tag'

Question

So I'm totally stumped by this one.

The problem

I have a powershell script (a .ps1 file) which at some point does the following:

Import-Module AzureRM

Login-AzureRmAccount -Credential $azureCredentials | out-null
Select-AzureRmSubscription -SubscriptionId $azureSubscriptionId -TenantId $azureTenantId | out-null

Write-Host (ConvertTo-Json((Get-AzureRmResource -Tag @{ "env"="dev"}) | Select Name, Location))

I run the script in a .NET console app by doing the following:

Dim process = New Process() With {.StartInfo = New ProcessStartInfo With {
    .FileName = "powershell.exe",
    .Arguments = "-ExecutionPolicy ByPass -file """ & _powershellScriptsPath & "\get-webapps.ps1",
    .UseShellExecute = False,
    .RedirectStandardOutput = True,
    .RedirectStandardError = True
}}

The script works fine on my laptop, whether it's run from the ISE or from the console app.

Then on my desktop, it works fine in ISE but fails in the console app, with the following error message:

Get-AzureRmResource : A parameter cannot be found that matches parameter name 'Tag'.

I can't figure this out.

Some insights

My $PSVersionTable is the same on both computers:

My laptop has version 6.1.0 of the AzureRm module:

While my desktop has version 6.5.0:

PS C:\WINDOWS\system32> Get-InstalledModule -Name AzureRm

6.5.0      AzureRM                             PSGallery            Azure Resource Manager Module

So there is a difference of versions here but -Tag does exist in 6.1.0 because in Powershell ISE the script does work. And it has to use 6.1.0 since it seems to be the only version that is installed(?).

Also the console app runs the same configuration in both Visual Studios (laptop/desktop) (at least as far as I can tell). Notably it's compiled as AnyCPU and runs in 32bit on both computers.

Answer 1

Looking at this it seems like -tag is missing pre 6.0.0 version of AzureRm. That is the root cause of the issue identified by:

get-command get-azurermresource -full

workaround would be to upgrade that version. you can find where the module is by doing:

get-module azurerm  | select modulebase

ps. another workaround would be to use odata query:

Get-AzureRmResource -ODataQuery "`$filter=tagname eq 'something'"
