Wrap request promise in try catch

[thomasrockhu]

It looks like a lot, but I just indented it and wrapped it all with a try catch to fix. Also bumping to 1.0.12

(node:4814) UnhandledPromiseRejectionWarning: Error: connect ETIMEDOUT 35.199.43.247:443

(node:4814) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
