Bluebird Promise: error is not a function

For some reason that I can't find out, this simple piece of code doesn't work.

new Promise(function (resolve, reject) {
  resolve();
}).then(function() {
  console.log("then: ")
}).error(function(err) {
  console.log("err: ", err)
})

It gives me

Uncaught TypeError: (intermediate value).then(...).error is not a function

If I replace error with catch, it runs fine. I would prefer not to catch though.

What am I missing here?

    If .error() does not exist, then you probably aren't using a Bluebird promise since .error() is not part of the Promise standard so you may just have a built-in promise instead of a Bluebird promise.

    Check to make sure that Bluebird is properly included in your project.
