Starting long task...');\n\n  try {\n    // You can pass the signal directly to other APIs like fetch() or fs.promises\n    await performLongTask(signal);\n    \n    res.writeHead(200, { 'Content-Type': 'text/plain' });\n    res.end('Task completed successfully!');\n  } catch (err) {\n    if (err.name === 'AbortError') {\n      console.log('Request was aborted by the client. Cleaning up...');\n    } else {\n      console.error('An error occurred:', err);\n      res.statusCode = 500;\n      res.end('Internal Server Error');\n    }\n  }\n});\n\n// Mock function representing an asynchronous task\nfunction performLongTask(signal) {\n  return new Promise((resolve, reject) =\u003e {\n    const timeout = setTimeout(() =\u003e {\n      resolve();\n    }, 5000);\n\n    // Manually listen for the abort event if the API doesn't support signals\n    signal.addEventListener('abort', () =\u003e {\n      clearTimeout(timeout);\n      reject(new DOMException('Aborted', 'AbortError'));\n    }, { once: true });\n  });\n}\n\nserver.listen(3000, () =\u003e {\n  console.log('Server running at http://localhost:3000/');\n});\n```\n\nSending get request works, but sending POST/PATCH with a request body always results in signal being aborted automatically at start of the requst.\n\n### How often does it reproduce? Is there a required condition?\n\nAlways\n\n### What is the expected behavior? Why is that the expected behavior?\n\nSignal should not aborted in any requests with body such as POST\n\n### What do you see instead?\n\nFor any request with body such as POST, signal is set to Aborted right from beginning.\n\n### Additional information\n\nThis was never an issue before 24.14","author":{"url":"https://github.com/ackava","@type":"Person","name":"ackava"},"datePublished":"2026-05-24T09:09:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/63532/node/issues/63532"}
