Jimp error: No matching constructor overloading was found

Question

I'm trying to create a meme command with my bot that uses Jimp to add text onto an image the user sends with the command. It works, but whenever something doesn't go to plan (eg someone not sending the image, someone not sending the text that needs to be applied to the image, etc.) it gets an error and crashes my bot. Here's my code:

case "meme":
const [topText, bottomText] = args.slice(1).join(" ").split(",");
msg.channel.startTyping();
if (!args[1]) msg.channel.send("You need to give the text you want to apply to the image!");
Jimp.read(msg.attachments.first(), (err, lenna) => {
  Jimp.loadFont(Jimp.FONT_SANS_128_WHITE).then(font => {
    if (err) console.log(err);
    lenna
      .resize(1280, 1080)
      .quality(100) // set quality
      .print(font, 75, 20, {
        text: topText,
        alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER,
        alignmentY: Jimp.VERTICAL_ALIGN_MIDDLE
      }, 1100)
      .print(font, 75, 900, {
        text: bottomText,
        alignmentX: Jimp.HORIZONTAL_ALIGN_CENTER,
        alignmentY: Jimp.VERTICAL_ALIGN_MIDDLE
      }, 1100)
      .write("./tmp/" + msg.author.id + ".jpg"); // save
  });
});
for (i = 0; i < (1); i++) {
  setTimeout(function () {
    msg.channel.send({
      files: ["./tmp/" + msg.author.id + ".jpg"]
    })
    msg.channel.stopTyping();
    for (i = 0; i < (1); i++) {
      setTimeout(function () {
        fs.unlinkSync("./tmp/" + msg.author.id + ".jpg")
      }, 3 * 1000)
    }
  }, 3 * 1000)
}
break;

Answer 1

Without know what specific error you're trying to handle against, the best way is to wrap your entire section of code in a try/catch . In the catch portion, you can console.warn the error and hopefully use the logs to debug this with more details.

Answer 2

You forgot to add a return statement to exit the logic if the user didn't follow the proper commands. When the user didn't provide the argument, I'm guessing msg.attachments.first() returns undefined which is why Jimp errors.

if (!args[1]) {
  return msg.channel.send("You need to give the text you want to apply to the image!");
} 

try { // it's good to have a try catch when dealing with asynchronous code
  Jimp.read(msg.attachments.first(), (err, lenna) => {
...
