VolleyError UnsupportedOperationException

Hello, I've been trying to implement a simple app to access some data behind authorization and update it.

I managed to get a simple HTTP request to work, but as soon as i add the Authorization header, I only get an UnsupportedOperationException back from GadgedBridge.

Maybe this is a bug in the app?
I attached my code with the url and token substituted:

Bangle.http("https://example.com/ID", {timeout: 5000, headers:{
Authorization: "TOKEN"}}).then(data=>{
  // Do stuff
}).catch(err=>{
  E.showMessage(err);
});

P.S. I noticed in the code for the app that there's no case to handle a PATCH http request. That might still be missing as well.
