How to ignore this error? As in stop it from sending

I made a feature in my discord bot to react to emojis with the same emoji, but when someone sends a message that isnt an emoji, it sends this error (it doesnt stop the bot, it just annoys me and floods the console)

Here it is:

client.on("message", message => {
  try {
    message.react(message.content);
  } catch (err) {
    console.log('')
  }
});

I tried looking for a way to check if the message is an emoji or not before running message.react(message.content);.

But i didn’t find a result.

And here’s the error:
UnhandledPromiseRejectionWarning: DiscordAPIError: Unknown Emoji

>Solution :

To ignore an error you can add .catch((err) => {}) to your code, for example:

message.react("").catch((err) => {})
