My first Tedx Talk: From Pain to Purpose – My TEDx Journey

on
August 30, 2025 – A date etched in my life for more than one reason. Exactly 11 years ago , I got engaged. And on that very same date this year, I received a life-changing opportunity: my first TEDx talk , hosted at GGI under the inspiring theme “Chase the Impossible.” Standing on that red dot, I felt a mix of emotions — excitement , nervousness , and the quiet ache of loss , having lost my wife, whose memories remain deeply rooted in my heart. In my talk, I shared a story born in the midst of COVID-19 — a time when Ms. Renu and I were both navigating personal grief in different ways. It was during this difficult phase that Mr. Chaitanya brought us together — blending Renu’s deep nutritional expertise with my technical background . That collaboration gave birth to a vision: A platform that could reduce the time it takes to create personalized diets , enabling dieticians to focus more on care, empathy, and connection — and patients to avoid long queues and delays.

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;
