Remove object from nested array failed

Question

A team has many projects. Im trying to delete a project, and so I need to delete it in marcsEquipa[] too.

TEAM SCHEMA

const EquipaSchema = new mongoose.Schema({

    trab1: { 
        type: Schema.Types.ObjectId,
        required: true,
        ref: 'Trab'
    },
    trab2: { 
        type: Schema.Types.ObjectId,
        required: true,
        ref: 'Trab'
    },
    trab3: { 
        type: Schema.Types.ObjectId,
        required: true,
        ref: 'Trab'
    },
    teamName: {
        type: String,
        required: true
    },
    marcsEquipa: [{
        type: Schema.Types.ObjectId,
        ref: 'Marcacao'
    }]
},
{collection: 'Equipas'})

Function Delete Project

exports.deleteMarc = async (req,res) => {

    console.log("Deleting Project..");
    console.log(req.params._id);
    console.log(req.params.equipa);
    try{
    console.log("1");
    const equipa = await 
    Equipas.updateOne({ _id: req.params.equipa}, { $pull: { marcsEquipa: { _id: req.params._id}}}, { multi: true });
    equipa.save();

    console.log("1");

    //await Marcacao.deleteOne({_id: req.params._id});
    res.status(200).json();
        
    console.log("1");

}catch(err) {
    res.status(400).json({message: err});
}

}

I've tried this and it manages to delete the Project but it doesn't delete it within the array of Projects in Team. Can anyone help?

You are trying to pull the item with _id property, but the items are just the string representation of ObjectId. So, instead of this:

{ $pull: { marcsEquipa: { _id: req.params._id }}}

do this:

{ $pull: { marcsEquipa: req.params._id }}
