    Try convert requestedDriverID to ObjectId(requestedDriverID)

    You need to convert the _id input to ObjectId.
    Here’s the updated code for your reference:

    
app.post("/fleetManagement",(req, res)=>{

const requestedDriverID = req.body.driverId;
console.log( requestedDriverID);

Driver.findOne({_id: ObjectId(requestedDriverID)  }, function(err, requestedDriverResult){
console.log(requestedDriverResult);
  res.render("fleetManagement", {
    reqDriver:requestedDriverResult
    });
  });
})
