I have a problem, in postman the result of the request is this:
Mensaje de Error en Postman

This is my Model

const mongoose = require("mongoose");
const mongoosePaginate = require("mongoose-paginate-v2");

const ComentariosSchema = mongoose.Schema({
    creator: String,
    comentario: String,
    created_at: { type: Date, default: Date.now },
    raiting: Number
});

const SoporteSchema = mongoose.Schema({
    folio: {
        type: Number,
        unique: true
    },
    documentos: String,
    servicio: String,
    descripcion: String,
    dueno: String,
    asignado: String,
    estado: String,
    prioridad: String,
    created_at: Date,
    MotivoCancel: String,
    CancelDate: Date,
    Cancelby: String,
    AsignDate: Date,
    comentarios: [ComentariosSchema]
});

SoporteSchema.plugin(mongoosePaginate);

module.exports = mongoose.model("Soporte", SoporteSchema);

This is my Controller:

const Soporte = require("../models/soporte");
async function addComnentarios(req, res) {
    try {
        const soporteId = req.params.id;
        const comentario = req.body;
        console.log("Comentario: ", comentario);
        if (!comentario || typeof comentario !== 'object' || Array.isArray(comentario)) {
            return res.status(400).send({ msg: "Comentario inválido" });
        }
        console.log("Req.body", req.body);
        const soporte = await Soporte.findById(soporteId);
        console.log(soporte);
        if (!soporte) {
            return res.status(404).send({ msg: "Ticket no encontrado" });
        }
        soporte.comentarios.push(comentario);
        const comentarioUpdated = await soporte.save();
        console.log(comentarioUpdated);
        res.status(200).send({ msg: "Comentario creado", comentarioUpdated });
    } catch (error) {
        res.status(400).send({ msg: "Error al crear el comentario", error });
    }
}

This should save the information. I compare with other answers and solutions, but only result in the same error. Can you help me pls?
