Attempting to use POST with a GET-only endpoint, or vice-versa

[zelikris]

I have the app set up and running per the instructions in the README but when the "Listen" button is pressed and a something is said and recorded, the following error is returned:

Attempting to use POST with a GET-only endpoint, or vice-versa

I know that the client access token I'm using is correct and corresponds to a valid agent. I'm using a Samsung S6 to test the app.
