a TryCatch block will catch errors from async function calls, so maybe you need to handle it there? Maybe it's in the error?

You can do something similar to this:

const getListingAsync = async (discogsClient: DiscogsClient, id: number): Promise<UserTypes.Listing> => {
  return new Promise(async (resolve, reject) => {
    discogsClient.marketplace().getListing(id, (err, data, rateLimit) => {
      if ((err && err !== null)) {
        err.rateLimit = rateLimit
        reject(err);
      } else if (data === null) {
        reject(err)}
      else {
        resolve(data);
      }
    });
  });
}

And use the getListingAsync func as below:

    try {
      const listing = await getListingAsync(discogsClient, parseInt(id, 10));

      console.log("FETCHED DISCOGS MARKETPLACE LISTING", {
        id,
        listing,
      });

      return listing;
    } catch (error: any) {
      console.log(error)
    }

The caught error will look something like:

{
  err: DiscogsError: Unknown error.
      at IncomingMessage.passData (/Users/xxx/node_modules/disconnect/lib/client.js:215:23)
      at IncomingMessage.emit (node:events:531:35)
      at IncomingMessage.emit (node:domain:488:12)
      at endReadableNT (node:internal/streams/readable:1696:12)
      at processTicksAndRejections (node:internal/process/task_queues:82:21) {
    statusCode: 429,
    rateLimit: { limit: 60, used: 65, remaining: 0 }
  },

Hope it helps

Don't have any experience with this myself, but disconnect can also return a Promise and can be used as a function for await if I understand this correctly https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function
