Trying to add a warning system to my mongodb, it works but says application didn't respond

Question

const {Client, CommandInteraction, MessageEmbed} = require("discord.js");
const db = require("../../Structures/Schemas/InfractionDB");

module.exports = {
    name: "warnings",
    description: "Give a warning",
    permission: "ADMINISTRATOR",
    options: [
                {
                    name: "target",
                    description: "Select a target.",
                    type: "USER",
                    required: true
                },
                {
                    name: "reason",
                    description: "Provide a reason.",
                    type: "STRING",
                    required: true
                },
                {
                    name: "evidence",
                    description: "Provide evidence.",
                    type: "STRING",
                    required: false
                },
            ],
        
    /**
     * 
     * @param {CommandInteraction} interaction 
     * @param {Client} client 
     */
    execute(interaction, client) {
        const{guild, member, options} = interaction
        const Target = options.getMember("target");
        const Reason = options.getString("reason");
        const Evidence = options.getString("evidence") || "None provided";

        const Response = new MessageEmbed()
        .setColor("RED")
        .setAuthor({name: "MOD BOT", iconURL: guild.iconURL()});

            db.findOne({GuildID: guild.id, UserID: Target.id}, async (err,data)=> {
                if(err) throw err;
                if(!data || !data.WarnData) {
                    data = new db({
                        GuildID: guild.id,
                        UserID: Target.id,
                        WarnData: [
                            {
                                ExecuterID: member.id,
                                ExecuterTag: member.user.tag,
                                TargetID: Target.id,
                                TargetTag: Target.user.tag,
                                Reason: Reason,
                                Evidence: Evidence,
                                Date: parseInt(interaction.createdTimestamp / 1000)
                            }
                        ],
                    })
                } else {
                    const WarnDataObject ={
                        ExecuterID: member.id,
                        ExecuterTag: member.user.tag,
                        TargetID: Target.id,
                        TargetTag: Target.user.tag,
                        Reason: Reason,
                        Evidence: Evidence,
                        Date: parseInt(interaction.createdTimestamp / 1000)
                    }
                    data.WarnData.push(WarnDataObject)
                }
                data.save()
            });
            Response.setDescription(`Warning Added: ${Target.user.tag} | ||${Target.id}||\n**Reason**: ${Reason}\n**Evidence**:${Evidence}`);
            guild.channels.cache.get("946217387336818699").send({embeds:[Response]});   
            
}}

originally this was routed to a different collection in my db. I've tried to convert it so I can see everything in one place. but it's taken me hours and don't seem to be getting anywhere. Like I said, the data is being stored on the db, but the Response is failing. Any ideas how to fix this? There are no errors in terminal
