Hi @redboyhun

Is it working outside of the module?
You can use something similar to the below

#after New-PASSession
$ThisSession = Get-PASSession

$Method = "GET"
$UrlPath = "API/Users/"

$Request = @{
    "Method"      = $Method
    "Uri"         = "$($ThisSession.BaseUri)/$UrlPath"
    "WebSession"  = $ThisSession.WebSession
    "ContentType" = "application/json"
}

Invoke-RestMethod @Request

As it is an error of the "500" type, assumption is that it is not an issue with the module.
Closing the issue based on this.
If assumption incorrect, comment here with the details to reopen.
