Tell us what’s happening:

can’t get the last test to pass even though everything works as far as i can tell.
I’m running my project locally, i have also tried to run everything in a webbrowser in gitpod.

NOTE
i tried passing in the optional parameters on the https://exercise-tracker.freecodecamp.rocks/ preview page, but this returns an [object Object] error.

my code:

const listener = app.listen(process.env.PORT || 3000, () => {
  console.log('Your app is listening on port ' + listener.address().port)
})

They are query string parameters, not route parameters.

Log out req.query in your last route handler to see them.

Ahh thanks a lot i see now, fixed the problem by requesting the query instead of params and changing my api get request path to ‘/api/users/:_id/logs’.
