  // Verify that the authentication bloc is available
  if (GetIt.instance.isRegistered<AuthenticationBloc>()) {
    final authenticationBloc = GetIt.instance.get<AuthenticationBloc>();

    // Only proceed if the user is authenticated
    if (authenticationBloc.state.isAuthenticated) {
      try {
        // Extract the language code from the authenticated user's profile
        final language = (authenticationBloc.state
                as UserAuthenticatedWithSelectedTenantState)
            .user
            .language
            .value
            .code
            .value;

        // Add language header only if the code is valid
        if (language.isNotEmpty) {
          options.headers['X-Language'] = language;
        }
      } catch (e) {
        // Silently handle any errors in language extraction
        // to prevent disrupting the API call
      }
    }
  }

  // Continue with the request
  handler.next(options);
