I’m using SAP’s Raylight RESTful SDK to get a list of universes from the BusinessObject Enterprise repository.

To get all of the universes, the request needs to be called repeatedly, incrementing the offset parameter until the request returns a Not Found [404] error.

Current approach:

$  baseUrl = 'http://<server>:6405/biprws/raylight/v1'  $  headers = @{} $  headers.Add("Accept", "application/json") $  headers.Add("Content-Type", "application/json") $  headers.Add("x-sap-logontoken", $  Token)  $  offset = 0 $  limit = 50  try {     do {          $  Path = "/universes?offset=$  offset&limit=$  limit"          $  response = Invoke-WebRequest "$  baseUrl$  Path" -Headers $  headers          ($  response | ConvertFrom-Json).universes.universe          $  offset += $  limit      } until ( $  response.StatusCode -eq [System.Net.HttpStatusCode]::NotFound ) } catch {     # catches 404 too     Write-Debug "StatusCode: $  ($  _.Exception.Response.StatusCode.Value__)" } 

While the code returns the expected results, I not sure that I like how the code will always exit via the catch. I could remove the try/catch, but that will leave the code exposed to other errors.

Is there a way to improve this?
