Azure DevOps REST API call retrieving only top 100 records and ContinuationToken getting as null

Question

I am using the below API call for retrieving all the CouldTests(1000+ cloudtests), but it is returning only 100 records. Here in the below code ContinuationToken is getting as null. Anything wrong here? I tried do..while also, but no difference. Any help is appreciated. Thanks in advance

$personalAccessToken = "Token"
$auth = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$($personalAccessToken)"))

$headers = @{}
$headers.Add("Authorization", "Basic $auth")
$Today = Get-Date -Format "yyyy-MM-dd"
$Tomorrow = (Get-Date).AddDays(1).ToString("yyyy-MM-dd")

do
{
    $uri = "https://{instance}/{collection}/{project}/_apis/test/runs?minLastUpdatedDate=$Today&maxLastUpdatedDate=$Tomorrow&releaseIds=12345678&continuationToken=$ContinuationToken&includeRunDetails=true&api-version=5.0"

    $TestRuns = Invoke-RestMethod -Uri $uri -Headers $headers -Method Get -ContentType "application/json" 
    $continuationToken = $TestRuns.Headers.'x-ms-continuationtoken'
    $Tests += $TestRuns
}
while ($continuationToken -ne $null)

You may try 'x-ms-continuation' and not 'x-ms-continuationtoken'. — DSpirit
I tried using 'x-ms-continuation', still it is getting as null. — Tinz
Have you tried outputting the result itself first? If there are no headers, there seems to be no HTTP response at all, so the request might be faulty. — DSpirit

You should get it with Invoke-WebRequest and not with Invoke-RestMethod:

do
{
    $uri = "https://{instance}/{collection}/{project}/_apis/test/runs?minLastUpdatedDate=$Today&maxLastUpdatedDate=$Tomorrow&releaseIds=12345678&continuationToken=$ContinuationToken&includeRunDetails=true&api-version=5.0"

    $TestRuns = Invoke-WebRequest -Uri $uri -Headers $headers -Method Get -ContentType "application/json" 
    $continuationToken = $TestRuns.Headers.'x-ms-continuationtoken'
    $Tests += $TestRuns
}
while ($continuationToken -ne $null)
