Turbopack Compiler Bug

[ryanelian]

I cannot share the source code for now. Nor do I have any reproduction.

However, this just happened to me. So I thought I'd report this before the bug is lost to the void.

import { ulid } from "ulid";

for (const s of scopes) {
	if (clientScopes.has(s)) {
		continue;
	}

	return authorizationError(
		"invalid_scope",
		"One or more requested scopes are invalid or not allowed for this client.",
	);
}

const authorizationCode = ulid();

Error in browser: 500 in 78ms

However, if I change the structure of the if-else:

for (const s of scopes) {
	if (!clientScopes.has(s)) {
		return authorizationError(
			"invalid_scope",
			"One or more requested scopes are invalid or not allowed for this client.",
		);
	}
}

const authorizationCode = ulid();

The app successfully compiled.

I thought it was an interesting compiler bug. I apologize for the lack of information.
