Cloudflare-Hudu Error 400

[cipherbytes9]

Invoke-RestMethod : The remote server returned an error: (400) Bad Request. At line:35 char:19

• ... $Result = Invoke-RestMethod -URI "$($Uri)?per_page=50&page=$Page" ...

• 
  + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException

I'm not sure what I'm missing to get the Cloudflare-Hudu script to connect. Looks like the page section is wrong but I cannot see how. Thoughts?
