That should work as well as `std::string` is convertible to `std::string_view`, and it's a best practice to use that conversion instead of `.c_str()` (because it's more performant and will not break if there are NUL bytes in the string – neither matters a lot here, but let's just stick to good practices across the codebase whenever we can)

Code after:

    if (!CompileFunctionForCJSLoader(
             env, context, code, filename, &cache_rejected, true, cached_data)
             .ToLocal(&fn)) {
      CHECK(try_catch.HasCaught());
      CHECK(!try_catch.HasTerminated());
      cjs_exception = try_catch.Exception();
      cjs_message = try_catch.Message();
      errors::DecorateErrorStack(env, cjs_exception, cjs_message);
    }
  }

  bool can_parse_as_esm = false;
  if (!cjs_exception.IsEmpty()) {
    // Use the URL to match what would be used in the origin if it's going to
    // be reparsed as ESM.
    Utf8Value filename_utf8(isolate, filename);
    std::string url = url::FromFilePath(filename_utf8.ToStringView());

    if (!String::NewFromUtf8(isolate, url.c_str()).ToLocal(&url_value)) {
      return;
    }
    can_parse_as_esm =
        ShouldRetryAsESM(realm, cjs_message->Get(), code, url_value);
    if (!can_parse_as_esm) {
