Unexpected token } in JSON

[beaglecodes]

Hi all! I'm a newb, spent hours trying to install this on OSX (hours because I had to google every error) and am so close now!

When I run sudo npm run start I get the following:

MacBook-Pro:dasher me$ sudo npm run start --python=python2.7

> dasher@1.4.1 start /Users/me/dasher
> node app.js

module.js:682
    throw err;
    ^

This is my JSON:

{"buttons":[
  {
    "name": "Tracker",
    "address": "[redacted]",
    "interface": "en0",
    "timeout": "60000",
    "protocol": "udp",
    "url": "https://maker.ifttt.com/trigger/button_pressed/with/key/[redacted]",
    "method": "POST",
    "json": true,
  }
]}

Any ideas for me? I tried googling the unexpected token error and did not get very far. :(

Try removing the trailing comma after "json": true. Trailing commas are not allowed in JSON: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Trailing_commas.

That was it -- thanks so much!
