This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled
with .catch(). The promise rejected with the reason:

This happened because my editor added import { TextDecoder } from "@edge-runtime/primitives". Removing the explicit import prevents the crash.
