Push/Pull values on nested array mongoose - arrays

Question

Im trying to update a value in a nested Array in a mongoose schema using express. I have the code required in place what i figuered i needed to update it, but the array doesn't get updated.
So the idea is to be able to have an array of data base schema objects with two fields, schemaName and schemaFields. I want to be able to update (add/remove)the values from schemaFields field of a specific schema object as needed.
I've already tried a bunch of stuff on here and elsewhere on the internet but nothing appears to work. I tried using findOneAndUpdate, findByIdAndUpdate etc.
My mongoose schema is as follows,
let databaseSchema = new Schema({
schemaName: { type: String },
schemaFields: [String]
});
let databaseSchemas = new Schema(
{
dbSchemas: [databaseSchema]
},
{
collection: 'databaseSchemas'
}
);
my update function is as follows,
schemasModel.mongo
.update(
{
_id: req.body.documentId,
'dbSchemas._id': req.body.schemaId
},
console.log('preparin to push the field \n'),
{
$push: {
'dbSchemas.$.schemaFields': req.body.newField
}
}
)
.then(() => {
res.send('new field added successfully');
});

So I solved it by removing the console.log() as a second argument to the model.update() function. Apparently this has to be the object with the operation.
The working code for the Model.update function is as follows,
schemasModel.mongo
.update(
{
_id: req.body.documentId,
'dbSchemas.schemaName': req.body.schemaToSearch
},
{
$push: {
'dbSchemas.$.schemaFields': req.body.newField
}
}
)
.then(() => {
res.send('new field added successfully');
});
