JavaScript React Basics (retired) Thinking in Components Properties Review

The quiz in Treehouse is saying this is incorrect??? How? It looks right to me

Fill in code to ensure the property name is a required string:

Player.propTypes = { name: React.PropTypes.string.isRequired, };

How the heck is this wrong?

The quiz is somewhat picky, it does not accept your answer if you include a comma at the end. Having a trailing comma is technically valid in JavaScript but it's not required so it seems the task was not designed with that in mind.

If you enter this exact text: React.PropTypes.string.isRequired with no commas or anything like that then your answer will be accepted.
