Challenge: Exercise Tracker

Link to the challenge:

Hello there,

I realise this challenge is not written in the best way to get past it. So, if I were you, I would have a look at what the tests expect: https://github.com/freeCodeCamp/freeCodeCamp/blob/master/curriculum/challenges/english/05-apis-and-microservices/apis-and-microservices-projects/exercise-tracker.english.md

Specifically, the tests expect duration to be a number, not a string.

I have got it thanks
