Tell us what’s happening: I’m not getting any errors in the console, but getting this error in the challenge page itself: Chaining query helpers should succeed The console shows the following, Your app is listening on port 3000 OPTIONS POST Here’s my code: const queryChain = (done) => { co…

You are returning the same person twice, it should be two different people. Not sure why, but you have Person.deleteOne in server.js but it should be Person.remove (line: 372 in server.js) Did you change it? Just to be clear, when I change it back to use the correct method in server.js your code…

[image] bahman778: let result = Person.find({favoriteFoods: foodToSearch}) are you returning this result? also, perhaps looking into “ hints ” for this might be more helpful, happy learning :slight_smile:

I’m not returning the result. That variable was left there when I was trying to return the result but got errors. Since the done() is called in the exec() so how can I return the variable?

perhaps try looking into hint: 8 from “hints” link that i shared and use it with a return in front of it, hopefully that would do,m happy learning :slight_smile:

Thanks @bappyasif for helping, unfortunately it still doesn’t work. My code looks like this now, const queryChain = (done) => { const foodToSearch = "burrito"; return Person.find({favoriteFoods: foodToSearch}) .sort({name: 1}) .limit(2) .select({age: 0}) .exec((err, data) => { if (e…

What’s the reason to return the result. Isn’t the returned result a Query Object taht needs to be chained to the functions that are called after the find method and then the call to the done() to return the result? Also the challenge prompt doesn’t mentiond anything about returning the result. The f…

[image] bahman778: const foodToSearch = "burrito"; why are you “hard coding” this variable value? isnt this supposed to be “modifiable”?! lets read from instructions find people who like the food specified by the variable named foodToSearch maybe you need to make it as such that “other …

const foodToSearch = "burrito"; but this is not my code, it was there already and other methods such as removeManyPeople have the same variable. Changing ‘const’ to ‘let’ didn’t help the issue either. Could you please answer my previous question so I can understand your logic of why to return from…

[image] bahman778: let foodToSearch = searchKey Person.find({ favoriteFoods: foodToSearch }) try it with “return” in front of it :slight_smile: [image] bahman778: Could you please answer my previous question so I can understand your logic of why to return from the function? I still don…

Thanks so much for helping. I did try it with the return in front of it and it still errors out with the same error but looking up online it seems to be a bad practice to return from the function in this way when the done() is being called. Could you please explain a bit more details about the call…

I put a console.log() inside the tester method in the server.js file, right before the call to res.json(data) I’m console logging data and it’s containing the query result that seems to be correct. so can someone please help me figure out what is causing the challenge to not pass and throw an error?…
