AggregateError: No Promise in Promise.any was resolved

The JavaScript exception "No Promise in Promise.any was resolved" occurs when all promises passed to Promise.any() are rejected. It is the only built-in usage of AggregateError.

In this article

Message

AggregateError: All promises were rejected (V8-based) AggregateError: No Promise in Promise.any was resolved (Firefox) AggregateError (Safari)

Error type

AggregateError

What went wrong?

Promise.any() only rejects when all promises passed to it are rejected. You should access errors to get the array of rejection reasons. See Using promises for more information on how to handle asynchronously rejected promises. This error is also raised when Promise.any() receives an empty iterable.

Examples

Empty iterable

js
Promise.any([]).catch((error) => { console.error(error); // AggregateError: No Promise in Promise.any was resolved });

Handling all rejections

js
const promises = [ fetch("/data-location1"), fetch("/data-location1"), fetch("/data-location1"), ]; Promise.any(promises) .then((value) => console.log(value)) .catch((error) => { // None of the fetches were successful for (const e of error.errors) { console.error(e); } }); // Using await async function fetchFirstSuccessful() { try { const value = await Promise.any(promises); console.log(value); } catch (error) { for (const e of error.errors) { console.error(e); } } }
