Google Plus moment post fails because of "vault" problem

[rafipass]

The following error is received from Google's servers
Error: Invalid string value: '{collection}'. Allowed values: [vault]
My code:

client
  .plus.moments.insert({userId: 'me'}, 'vault', req.body.message)
  .withAuthClient(gOauth)
  .execute(callback);

The same error occurs no matter what type of object specified for the second argument.

  {collection: 'vault'}
  ["vault"]
  {vault: []}

and even when I pass vault in as it's defined your library:

  var vault = { 
    type: 'string',
    required: true,
    enum: [ 'vault' ],
    location: 'path'
  }

all produce an identical error.

The only similar error I could find was here: https://code.google.com/p/google-plus-platform/issues/detail?id=658
(although this error is for the clientside javascript library)

All parameters specified by the API documentation should be part of the same object. So instead of
.plus.moments.insert({userId: 'me'}, 'vault', req.body.message)
you should probably have something like
.plus.moments.insert({userId: 'me', collection: 'vault'}, req.body.message)
