I need help with Exercise Tracker project

these two errors keep showing when submitting and this is my code

The date property of any object in the log array that is returned from
GET /api/users/:id/logs should be a string.
Use the dateString format of the Date API.

You can add from to and limit parameters to a GET /api/users/:_id/logs
request to retrieve part of the log of any user. from and to are dates in yyyy-mm-dd
format. limit is an integer of how many logs to send back. (Test timed out)
