使用 repl.it 的 Discord.js 数据库

Question

I made a database script in repl.it and it's working but I keep getting null and then users database here is my code:

client.on("message", async (message) => {
    if (message.content.toLowerCase().startsWith("#مخالفات")) {
        var pfpMember = message.mentions.members.first() || message.member;

        const violation = await db.get(`wallet_${message.mentions.members.first()}`);

        if (violation === null) violation = "العضو ليس لديه اي مخالفات";

        const pembed = new Discord.MessageEmbed()
            .setTitle(`شرطة لوس سانتوس`)
            .setDescription(`المخالفات المرورية :` + violation)
            .setColor("RANDOM")
            .setFooter("شرطة لوس سانتوس")
            .setThumbnail(pfpMember.user.displayAvatarURL());
        message.channel.send(pembed);
    }
});

And here is a screenshot:

The issue is that you cannot reassign violation as it is a constant, not a variable.

Using the following should solve the issue:

client.on("message", async (message) => {
    if (message.content.toLowerCase().startsWith("#مخالفات")) {
        var pfpMember = message.mentions.members.first() || message.member;

        let violation = await db.get(`wallet_${message.mentions.members.first()}`);

        if (violation === null) violation = "العضو ليس لديه اي مخالفات";

        const pembed = new Discord.MessageEmbed()
            .setTitle(`شرطة لوس سانتوس`)
            .setDescription(`المخالفات المرورية :` + violation)
            .setColor("RANDOM")
            .setFooter("شرطة لوس سانتوس")
            .setThumbnail(pfpMember.user.displayAvatarURL());
        message.channel.send(pembed);
    }
});
