Description
Node now allows using require() to import ES modules, ERR_REQUIRE_ESM is not triggered.
But if the module containes top-level await, ERR_REQUIRE_ASYNC_MODULE is triggered and it's not handled.
The following gulpfile.mjs contains top-level await.
In Node 20, this works.
In Node 22, this throws ERR_REQUIRE_ASYNC_MODULE.
Sample of gulpfile
import { readFile } from 'fs/promises';
const packageJson = await readFile('package.json', 'utf8');
export function test(cb) {
console.log(packageJson);
cb();
}
export default test;Terminal output
$ gulp
Error [ERR_REQUIRE_ASYNC_MODULE]: require() cannot be used on an ESM graph with top-level await. Use import() instead. To see where the top-level await comes from, use --experimental-print-required-tla.
