javascript
Unhandled promise rejection crashing process
UnhandledPromiseRejection.*promise rejected.*no.*handler
Fixes
- 1.Add .catch() to every promise chain, or use try/catch with async/await
- 2.Set global handler: process.on('unhandledRejection', (reason, promise) => { log and gracefully shut down })
- 3.In Node 15+, unhandled rejections crash by default — ensure all async paths have error handling
