     *   a certain AWS error occurred.

     *   'ChainableTemporaryCredentials' and the target role doesn't exist,
     *   the error message that shows up by default is super misleading
     *   (https://github.com/aws/aws-sdk-js/issues/3272). We can fix this because
     *   the exception contains the "inner exception", so we unwrap and throw
     *   the correct error ("cannot assume role").
     *
     * The wrapping business below is slightly more complicated than you'd think
     * because we must hook into the `promise()` method of the object that's being
     * returned from the methods of the object that we wrap, so there's two
     * levels of wrapping going on, and also some exceptions to the wrapping magic.
