I'm new to Pulsar and I'm having the exact same issue, when running the
official examples using:
* pulsar-client: 1.6.2
* libpulsar/2.10.1_1
* Node 18.8.0
* Apache Pulsar 2.10.1
Official `producer.js` example:
```javascript
const Pulsar = require('pulsar-client');
(async () => {
// Create a client
const client = new Pulsar.Client({
serviceUrl: 'pulsar://localhost:6650',
});
// Create a producer
const producer = await client.createProducer({
topic: 'my-topic',
});
// Send messages
for (let i = 0; i < 10; i += 1) {
const msg = `my-message-${i}`;
producer.send({
data: Buffer.from(msg),
});
console.log(`Sent message: ${msg}`);
}
await producer.flush();
await producer.close();
await client.close();
})();
```
Output of running `node producer.js`:
```

I installed the C++ client with the installation instructions here:
https://pulsar.apache.org/docs/client-libraries-cpp/#compilation
Let me know if I should open another issue. I don't know C++ but it appears
that the patch added in https://github.com/apache/pulsar-client-node/pull/85
isn't in current `master`:
https://github.com/apache/pulsar-client-node/blob/8893e47e87118f89ad324ccf5e60785eabc5b34d/src/Client.cc
-- unsure if this is related or not.
Thanks.
