When using the following endpoint, pagination works

> Invoke-RestMethod -Method GET -Headers $headers -Uri ($uri + "/tickets?$fsUpdatedSince&per_page=100&include=stats,tags") -ResponseHeadersVariable 'ticketsResponseHeader'


> $ticketsResponseHeader

Key                             Value
---                             -----

Transfer-Encoding               {chunked}
Connection                      {keep-alive}
status                          {200 OK}
x-freshservice-api-version      {latest=v2; requested=v2}
Link                            {<https://xxxxxxxx.freshservice.com/api/v2/tickets?updated_since=2025-06-01T10:40:21Z&per_page=100&include=stats,tags&page=2>; rel="next"}

However when using the /tickets/filter endpoint, the responseheader does not include the link attribute, so the built in functionality of Powershell 7 Invoke-RestMethod, FollowRelLink does not work. It would seem to be a bug?

$invokeParams = @{
    method = "GET"
    headers = $headers
    uri = ($uri + '/tickets/filter?per_page=100&query="status:2%20OR%20status:3%20OR%20status:6%20OR%20status:7%20OR%20status:8%20OR%20status:9%20OR%20status:10"') 
    verbose = $true
    MaximumRetryCount = 5
    RetryIntervalSec = 10
}

> $result = Invoke-RestMethod @invokeParams -ResponseHeadersVariable 'myresponseHeader' -FollowRelLink

> $myresponseHeader
