How often does it reproduce? Is there a required condition?

Hey, I've marked this issue as stalled (though that bot doesn't appear to work), just so collaborators know that this issue is waiting for more information.

@joyeecheung wdyt? Should we replace the else with else if (getOptionValue('--experimental-require-module')) in

node/lib/internal/modules/cjs/loader.js

Lines 1377 to 1381 in 0301309

	} else {
	const {
	wrap,
	namespace,
	} = cascadedLoader.importSyncForRequire(mod, filename, source, isMain, mod[kModuleParent]);

[joyeecheung]

That function should only be used if the option is turned on in the first place (otherwise it should’ve gone elsewhere to throw ERR_REQUIRE_ESM instead of going into this function), I am not sure whether that solves anything without more information of the repro

[RedYetiDev]

I am not sure whether that solves anything without more information of the repro

@Mongsplaatjies can you provide a minimal reproducible example of the code that caused this error?

For reference, the failing assertion is:

node/lib/internal/modules/esm/loader.js

Line 329 in 0debdac

assert(getOptionValue('--experimental-require-module'));

I'm able to reproduce thanks to @dgozman with the following script:

rm -rf repro
mkdir repro
cd repro

echo 'import "fs"' > imported.ts
node -e 'require("./imported.ts")'

cd ..
rm -rf repro
