Exercise Tracker Test Failing for no apparent reason

Hi All,

I am having issue with the Exercise Tracker test failing for the requirement below. I don’t see any reason it’s failing because the returned object when I add an exercise is the same as what the example App gives.

Does anyone know what I am doing wrong?

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.

My project link is:


I appreciate the help.


You are returning a userId: key when the test appears to be looking for an _id: key.

Thank you that solved it!!

The reason I used userId instead of _id is, that is what the example App is returning the ID as. Look at the returned object below that I got from the examples App. It looks like there are some inconsistencies between what the test requires and what the example shows and also general vagueness in this exercise.

{"userId":"5ec3c38cc530e526ad533782","description":"blaaaaaaaaaaaaa","duration":45345345,"date":"Tue Jun 02 2020","username":"5WfZFvsBK"}

Thanks again!
