Firebase SyntaxError when deploying functions

I started a firebase functions project last week and it all worked like a charm for the first couple of days. This morning however I started having this error whenever I run the firebase deploy --only functions command:

Error: Error occurred while parsing your function triggers.

SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:387:25)
    at Object.Module._extensions..js (module.js:422:10)

    at Module._compile (module.js:413:34)
    at Object.Module._extensions..js (module.js:422:10)

I am now running the Firebase cli tools version 3.5.0 and Node 5.5.0

Anyone knows what's happening?
