        required: true
    }
});

module.exports = mongoose.model("Message", MessageSchema);

i expect to be some text in here

Answer 1

the problem was that i was no passing an object;

sendMessage: async (root, { senderId, receiverId, messageText }, { User, Message }) => {
            const newMessage = await new Message({senderId, receiverId, messageText}).save();
            return newMessage;
        },
