Retryable Exception

I'm getting the following error when trying to create a producer with Pulsar Node JS client:

```
node:internal/process/promises:288
triggerUncaughtException(err, true /* fromPromise */);
^

[Error: Failed to create producer: Retryable]
```

Start by reproducing producer creation with the Pulsar Node JS client and record the client, broker, and producer configuration involved in the Retryable error. The issue does not name a file or test; completion would require identifying the cause and confirming that producer creation succeeds or that the error is actionable.
