I have an issue.

I should use the mongoose find() method for some queries. While using the find() method, when I give filter find method works but it doesn't give me value/values.

const messages = await MessageSchema.find({sessionId: sessionId}, {__v: 0, _id: 0, updatedAt: 0}).exec();

The above code is my find method. This code gives me as value, empty array. []

But in this code,

const messages = await MessageSchema.find({}, {__v: 0, _id: 0, updatedAt: 0}).exec();

give me an array and all of the messages are in the array.

But I should use filtering.

This is my message Schema.

const mongoose = require('mongoose');

var schema = new mongoose.Schema({
    participant_name: {type: String},
    message: {type: String},
    sessionId: {type: String},
    participantId: {type: Object}
}, {
    timestamps: true
});


module.exports = mongoose.model("Message", schema)

Could you help me please?
