camunda8-reproduction

A minimal reproduction for demonstrating how canceled long-poll promises are logged as errors during graceful shutdown in @camunda8/sdk

Prerequisites

• Node.js v22 (as specified in the package.json)

Setup

1. Clone the repo
2. Install dependencies (npm install)
3. Update the Camunda connection placeholders in reproduction.ts

Usage

Run the reproduction script:

npm run start

This will:

1. Fetch and log the Camunda 8 topology
2. Start a single-job worker of type test-job
3. Wait 5 seconds to activate a job
4. Trigger a graceful shutdown (worker.stop())
5. Wait 1 second to let the canceled long-poll promise surface the errors

Expected Behavior

When the worker shuts down gracefully, any in-flight activation requests should be canceled silently without logging errors.

Observed Behavior

Instead, the SDK logs two errors:

error: Error during job worker poll
error: Promise was canceled
