Resolved Error - Azure Powershell failed to get token from Token Cache. Getting You cannot call a method on a null-valued expression

on

 Recently, I was working on an Azure Powershell Script in which I was getting the Cached Token and it was working fine for a long time and it started failing recently.

Here is the code that I was using in my powershell script:

    Write-Host "Getting Az Context"
    $azContext = Get-AzContext
    Write-Host "Displaying context"

    #$rmAccount = Add-AzureRmAccount -SubscriptionId $subscriptionId 
    #$tenantId = $azureRmContext.Tenant.Id
    $tokenCache = $azContext.TokenCache
    $cachedTokens = $tokenCache.ReadItems() `
        #| where { $_.TenantId -eq $tenantId } `
        Sort-Object -Property ExpiresOn -Descending
	
    $cachedTokens[0].AccessToken

Now, I started getting the error "You cannot call a method on a null-valued expression". I was clear that my Token Cache is getting expired and then I googled about the issue and I find the following useful github links: And finally, I implemented the following solution:

Solution: 

    $currentAzureContext = Get-AzContext
    $azureRmProfile = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile;
    $profileClient = New-Object Microsoft.Azure.Commands.ResourceManager.Common.RMProfileClient($azureRmProfile);
    $profileClient.AcquireAccessToken($currentAzureContext.Subscription.TenantId).AccessToken;
