mongodb - saving a findOneAndUpdate entry in mongoose and mongDB

Question

I am using mongoose to check if a user input already exists in my database, and if it doesn't I want to create a new record with that user input together a processedInput (done by another function elsewhere). Below is the findOneAndReplace function I have set up to accomplish this:

User.findOneAndUpdate({original: userInput},{original: userInput, processString: outPut} , {new: true, upsert: true}
  );

Everything seems to run fine but when I check my mongoDB, my collections are not being updated.

I have tried setting upsert to true and using User.save() with no success. There are no connection issues with the database.

Answer 1

This resolved my issue: I added a callback function as an argument to the findOneAndReplace.

callback=(error,data)=>{if(error){console.log(error}
else {console.log(data)}



  User.findOneAndUpdate({original: userInput},{original: userInput, processString: outPut} , {new: true, upsert: true}, callback);
