Error: The request resource /2010-04-01/Accounts/:Account-SID/Calls.json was not found

Hello,

I'm trying to execute the server and run the web application on my local server, using ngrok as my online publisher for my app. When I submit the information to execute the code I get a 500 Error:

{"readyState":4, responseText":{"status":404, \message":"The requested resource /2010-04-01/Accounts/{myAccoundID}/Calls.json was not found,"code":20404,"moreInfo":\https://www.twilio.com/docs/errors/20404\"}","status":500,"statusText":"Internal Server Error"}

OS: I'm running a debian Linux 4.9.35 Jessie
Platform: Raspberry Pi model B+

I can't install the heroku toolbelt on either my windows machine or my raspberry pi machine, how do I ensure the call isn't returning a 500 error?
