Async Error

Definitions

1. An error that occurs in asynchronous execution, often outside the original call site that scheduled the work. Async errors are harder to debug than synchronous ones because stack traces, timing, and ownership may be split across promises, callbacks, tasks, or event loops.

   In plain English: An error that happens during asynchronous work rather than in the immediate call flow.

   Example: "The handler looked fine until an uncaught async error in a background await chain crashed the request after the response had already started."
