Mongoose findOne produces no output or delivers whole database

Question

I created a function to create a profile document, based on a schema, into mongoDB, which works so far:

const createUpdateProfile = (req, res) => {
    let uuid = req.user.identities[0].id;
    let provider = req.user.identities[0].provider;
    let email = req.user.email;
    let firstName = req.user.name.split(' ').slice(0, -1).join(' ');
    let lastName = req.user.name.split(' ').slice(-1).join(' ');
    let pictureUrl = req.user.picture;
    let profileToSafe = new Profile({
        uuid: uuid,
        provider: provider,
        email: email,
        firstName: firstName,
        lastName: lastName
    });
    const profile = Profile.findOne({ uuid });
    if (profile !== null) {
        profileToSafe.save();
    }
    res.status(200).send('successful operation');
}

I checked the DB and the document has been stored there.

But I cannot read it.

const getProfile = (req, res) => {
    let uuid = req.user.identities[0].id;
    Profile.findOne({ uuid: uuid }), function (obj) { console.log(obj) }, function (err) { console.log(err) };
    res.status(200).send('successful operation');
}

There is simply no console log output. Not even a null or an error.

I did as mentioned here also I tried to console log findOne function but it returns kind of the whole database, including the authentication data.

You have close the parameter list to the findOne method too early in your second snippet.

Profile.findOne({ uuid: uuid }), function (obj) { console.log(obj) }, function (err) { console.log(err) };

should be

Profile.findOne({ uuid: uuid }, function (obj) { console.log(obj) }, function (err) { console.log(err) });
