Facing error when running a PowerShell script using mggraph

Question

I am facing issue in fetching lastsignindate from azure ad using mggraph it returns error of 404 not found whereas user is present in azure ad.

The script i am sharing has some fields blank for security reasons:

Function to authenticate with Microsoft Graph

function Get-GraphToken {
param (
[string]$tenantId,
[string]$clientId,
[string]$clientSecret,
[string]$authUrl
)
$authBody = @{
grant_type = "client_credentials"
scope = "https://graph.microsoft.com/.default"
client_id = $clientId
client_secret = $clientSecret
}
try {
$tokenResponse = Invoke-RestMethod -Method Post -Uri $authUrl -ContentType "application/x-www-form-urlencoded" -Body $authBody
return $tokenResponse.access_token
} catch {
Write-Error "Failed to authenticate with Microsoft Graph: $_"
return $null
}
}

Function to get the most recent LastLogon attribute from all domain controllers

function Get-LastLogon {
param (
[string]$userName
)
$dcs = Get-ADDomainController -Filter * | Select-Object -ExpandProperty HostName
$lastLogon = 0
foreach ($dc in $dcs) {
try {
$user = Get-ADUser $userName -Server $dc -Properties LastLogon
if ($user.LastLogon -gt $lastLogon) {
$lastLogon = $user.LastLogon
}
} catch {
Write-Error "Failed to retrieve LastLogon from $dc for $userName $_"
}
}
if ($lastLogon -ne 0) {
return [DateTime]::FromFileTime($lastLogon)
} else {
return $null
}
}

Function to get last sign-in date from Azure AD using User ID

function Get-UserLastSignIn {
param (
[string]$userId,
[hashtable]$headers
)
try {

Get the user's sign-in activity using userId

$userInfo = Invoke-RestMethod -Uri "https://graph.microsoft.com/v1.0/users/$userId?$select=signInActivity" -Headers $headers
if ($userInfo.signInActivity -and $userInfo.signInActivity.lastSignInDateTime) {

Return the lastSignInDateTime

return [DateTime]::Parse($userInfo.signInActivity.lastSignInDateTime)
} else {
Write-Warning "No sign-in activity available for user with ID $userId."
return $null
}
} catch {
Write-Error "Failed to retrieve sign-in data for user with ID $userId $_"
return $null
}
}
