AkousaUnhandledPromiseRejectionA Promise was rejected but no .catch() handler or try-catch block was present to handle the rejection.
A Promise rejected and no rejection handler was attached. This happens when you forget .catch() on a promise chain, do not use try-catch with await, or fire-and-forget async functions without error handling.
Add .catch() to all promise chains. Use try-catch around await calls. Add a global handler: process.on('unhandledRejection', handler) for Node.js or window.addEventListener('unhandledrejection', handler) for browsers.
