// Flags: --no-experimental-require-module
// Previously, this tested that require(esm) throws ERR_REQUIRE_ESM, which is no longer applicable
// since require(esm) is now supported. The test has been repurposed to ensure that the old behavior
// is preserved when the --no-experimental-require-module flag is used.
