Why does my Array.prototype.find() return undefined?

I have a route handler in which I am attempting to find a user's collection of club objects, then find the specific club object using Array.prototype.find(). I have no idea why it is always returning undefined. Can anyone see what I am doing wrong?

router.get('/club', async (req,res) => {      try {            console.log(req.query.club);           // 6008d7537ea5c22b61dc616b                    const { clubs } = await User.findOne({ spotifyId: req.query.id }).populate('clubs').select('clubs');                    console.log(clubs);           // [{"_id":"6008d7537ea5c22b61dc616b","name":"asfasfs","description":"sdfasfa","privacy":"private","frequency":"bi-weekly","__v":0},{"_id":"6008ec8026900630c24fd533","name":"asfasfdsasf","description":"asdfasfdsf","privacy":"private","frequency":"monthly","__v":0}]                    let club = clubs.find(currentClub => (             currentClub._id === req.query.club          ));            console.log(club)          // undefined                    res.send(club)      }      catch {          return res.status(400).send('No club found with given id')      }  })
