Node Module Updating Deal Problem

Trying to update a deal, passing deal id and new deal value:

pipedrive.Deals.update({id: 3661}, {value: 200}, function(updateErr, updateData) {
if (updateErr) {
} else {
console.log(‘Product was updated’, updateData);

Error I’m getting:
Error: Pipedrive API error:There was an error in your request. Please refer to the API documentation and check your request validity against the documentation.

The node module documentation only gives example of updating a dealProduct.
And this: pipedrive.{Object}.update (id, data, [fn callback])

Link to documentation

Any ideas of what I’m doing wrong?

Have you had a chance to test this directly on the reference page to see if it doesn’t work for you there as well?
