APIs and Microservices Projects - Exercise Tracker problem

Tell us what’s happening:

My app can’t pass test “I can add an exercise to any user by posting form data userId(_id), description, duration, and optionally date to /api/exercise/add. If no date supplied it will use current date. App will return the user object with the exercise fields added.” ,
but if I add data, it works, what is the problem?

When you request an exercise post you only have to send the data of the current exercise over. You are sending the entire log.
