未捕获的 Promise Rejection SyntaxError: Unexpected token u in JSON at position 0

Question

I am trying to log a arg to json but its giving me 0 error means it not getting input or undefined but in console.log it displays the args clearly what can i do?

const fs = require('fs')

module.exports = {
    name: "write",
    category: "fun",
    description: "Save 1 message in our database",
    run: async (client, message, args) => {
        let save = args.join(" ");
        console.log(save)

        let msgs = JSON.parse(fs.readFileSync("./message.json", "utf8"));

        msgs[message.guild.id] = {
            msgs: save
        };
        await fs.writeFile("./message.json", JSON.stringify(msgs), (err) => {
            if (err) throw err;
            message.channel.send("message logged");

        });

    }

}

It seems the message.json isn't a valid JSON. Instead, wrap the code in a try-catch so that error can be handled here. Also, try to log the msgs so that output can be viewed.

try {
 let msgs = JSON.parse(fs.readFileSync("./message.json", "utf8"));

 msgs[message.guild.id] = {
   msgs: save
 };
 await fs.writeFile("./message.json", JSON.stringify(msgs), (err) => {
  if (err) throw err;
  message.channel.send("message logged");
 }); 
} catch(e) {
  console.log(e.message);
}
