Solution

  • If you check the discord.js source code, you can see that they try to silently ignore errors when their code requires the worker_threads module. They simply omit the usual (error) part after catch:

    try {
  // Test if worker threads module is present and used
  data = require('worker_threads').workerData || data;
} catch {
  // Do nothing
}

    However, this only works in newer versions of JavaScript; older ones will throw a SyntaxError. So, you must be using an older version of Node, because optional catch binding is only available in Node.js v10+.

    The following is an example in Node v8:

    // using Node v8
try { error } catch { console.log('oops') }

    ⬇⬇ result ⬇⬇

    try { error } catch { console.log('oops') }
                    ^

SyntaxError: Unexpected token {

    While it just works fine in Node v10+:

    // using Node v16
try { error } catch { console.log('oops') }

    ⬇⬇ result ⬇⬇

    oops

    To solve this, you need to update your Node version to at least v12, as mentioned in the discord.js docs:

    v12 requires Node 12.x or higher, so make sure you're up-to-date. To check your Node version, use node -v in your terminal or command prompt, and if it's not high enough, update it! There are many resources online to help you with this step based on your host system.
