[aryamohanan]

Environment Information

• OS: macOS (M1 architecture)
• Node.js Version: v23
• NPM Version: 10.9.0
• node-rdkafka Version: 3.3.0

Steps to Reproduce

1. Upgrade node-rdkafka to version 3.3.0
2. Run the application with Node.js v23
3. The following error occurs:

Error Log

/artifacts/node_modules/node-rdkafka/lib/error.js:408
  } else if (!util.isError(e)) {
                ^
TypeError: util.isError is not a function
    at new LibrdKafkaError (/artifacts/node_modules/node-rdkafka/lib/error.js:408:20)
    at Function.createLibrdkafkaError [as create] (/artifacts/node_modules/node-rdkafka/lib/error.js:456:10)
    at /artifacts/node_modules/node-rdkafka/lib/kafka-consumer.js:510:29

Expected Behavior

The library should work without issues after upgrading to v3.3.0 in Node.js v23.

Actual Behavior

The application crashes at runtime due to TypeError: util.isError is not a function.

Additional Context

This issue seems to be caused by util.isError() was deprecated and removed in v23, see nodejs/node@dc379626ab
