Tell us what’s happening:

I keep getting a TypeError: Cannot read properties of null (reading 'log') for test case 7 when trying to pass the tests. The FCC test is also showing Test timed out. Any help is appreciated.

Here is my code for this exercise:

app.post('/api/users/:_id/exercises', async (req, res) => {
	try {
		const update = {
			date: req.body.date ? 
			(new Date(req.body.date)).toDateString() :
			(new Date()).toDateString(),
			duration: parseInt(req.body.duration),
			description: req.body.description
		};
		var Docs = await Exercise.findOne({_id: req.body[':_id']});
		Docs.log.push(update);
		await Docs.save();
		console.log("checking for id: " + req.body[':_id']);
		res.json({ 
			username: Docs.username,
			description: update.description,
			duration: update.duration,
			date: update.date,
			_id: req.body[':_id']
			
		});
	} catch(err) {
		return console.log(err);
	}
})

the only log I see is here, you should maybe check what value Docs have with a console.log

3

When adding the console.log(Docs) it returns null.

I’m able to generate the correct response object in my local environment but am running into issues when trying to pass the test.

4

where does Exercise come from?

5

Here is my Mongoose schema:

const Schema = mongoose.Schema;

const ExerciseSchema = new Schema({
	username: { type: String, required: true },
	_id: { type: String, required: true },
	count: Number,
	log: [{description: String, duration: Number, date: Date}]
});

// Create a Model
let Exercise = mongoose.model("Exercise", ExerciseSchema);
6

try to think on when Docs could get a null value (when findOne would return null), and is that expected? and you need to deal with it properly. Or is there something going wrong with the database?

7

I know if there is no id match findOne returns null which I would expect, but I’m not sure how to deal with it. I tried adding a conditional block but FCC still throws the Test time out.

app.post('/api/users/:_id/exercises', async (req, res) => {
	try {
		const update = {
			date: req.body.date ? 
			(new Date(req.body.date)).toDateString() :
			(new Date()).toDateString(),
			duration: parseInt(req.body.duration),
			description: req.body.description
		};
		
		var Docs = await Exercise.findOne({_id: req.body[':_id']});
		if (Docs != null) {
			Docs.log.push(update);
			await Docs.save();
			res.json({ 
				username: Docs.username,
				description: update.description,
				duration: update.duration,
				date: update.date,
				_id: req.body[':_id']
			});
		}
	} catch(err) {
		return console.log(err);
	}
})

you are not giving a response if Docs is null, you must always give a response

ah okay, I added an else block and the test is passing now.

app.post('/api/users/:_id/exercises', async (req, res) => {
		const update = {
			date: req.body.date ? 
			(new Date(req.body.date)).toDateString() :
			(new Date()).toDateString(),
			duration: parseInt(req.body.duration),
			description: req.body.description
		};
		
		var Docs = await Exercise.findOne({_id: req.body[':_id']});
		if (Docs != null) {
			Docs.log.push(update);
			await Docs.save();
			res.json({ 
				username: Docs.username,
				description: update.description,
				duration: update.duration,
				date: update.date,
				_id: req.body[':_id']
			});
		} else {
			res.send("No ID found");
		}
})

I’m running into issues with test case 8 now, but will post again later if I can’t work through it. Thanks for the help!
