failed to read stream, no exist StreamNotFoundError: stream not found

Question

As per documentation:

https://developers.eventstore.com/clients/grpc/reading-events.html#reading-backwards-1

under: Checking if the stream exists

const events = client.readStream("user", {
  direction: FORWARDS,
  fromRevision: BigInt(10),
  maxCount: 20,
});

try {
  for await (const resolvedEvent of events) {
    console.log(resolvedEvent.event?.data);
  }
} catch (error) {
  if (error instanceof StreamNotFoundError) {
    return;
  }

  throw error;
}

i do get:

failed to read stream, no exist StreamNotFoundError: user not found

Their tutorials seems outdated for me.

Q: Is there a way to check if a stream exist ( and maybe add if not?) in event store in 2022?

Edit 2:

after the attempts, it still shows with the provided answer: node:events:505 throw er; // Unhandled 'error' event ^

StreamNotFoundError: user not found
    at ReadStream._transform (game\node_modules\@eventstore\db-client\dist\streams\utils\ReadStream.js:50:32)

I am not sure what you have in your database, but I quickly copied the samples code and it works as expected

const {EventStoreDBClient, FORWARDS, StreamNotFoundError, START} = require("@eventstore/db-client");

async function main() {
    const CLOUD_ID = "ca1loplo0aepjgt215o0";
    const client   = EventStoreDBClient.connectionString`esdb+discover://${CLOUD_ID}.mesdb.eventstore.cloud`;

    const events = client.readStream("doesntexist", {
        direction:    FORWARDS,
        fromRevision: START,
        maxCount:     20,
    });

    try {
        for await (const resolvedEvent of events) {
            console.log(resolvedEvent.event?.data);
        }
    } catch (error) {
        if (error instanceof StreamNotFoundError) {
            console.log("Stream not found");
            return;
        }

        throw error;
    }
}

main().then(() => console.log("done"));

When I run it I get:

Stream not found
done
