Exception has occurred. DataException (errorBadRequest)

[Zohalmohal]

Hello!
I tried to run your code but it gives me the following error:

Exception has occurred.
DataException (errorBadRequest)

The error occurs in this part of the code:

final favoritePairProvider = FutureProvider<FavoritePair>((ref) async {
  final cancelToken = CancelToken();
  ref.onDispose(() => cancelToken.cancel());

  final settings = ref.watch(cryptoSettings);
  String exchangeName = settings.maybeWhen(
      data: (details) => details.favoriteExchange, orElse: () => "");
  String pairName = settings.maybeWhen(
      data: (details) => details.favoritePair, orElse: () => "");

  if (exchangeName.isEmpty || pairName.isEmpty) {
    throw DataException(message: LocaleKeys.errorSomethingWentWrong);
  }

  Pair pair = Pair(pair: pairName, exchange: exchangeName);
  try {
    PairSummary pairSummary = await ref
        .read(cryptoRepository)
        .getPairSummary(exchangeName, pairName, cancelToken: cancelToken);
    return FavoritePair(pair: pair, pairSummary: pairSummary);
  } on DataException catch (error) {
    if (error.message == LocaleKeys.errorRequestNotFound) {
      ref.read(cryptoSettings.notifier).verifyFavoritePair();
    }
    throw error;
  }
});

I also changed the .env-example file to .env and copied my gotten API private key like below into it:

API_KEY=ddTaK3jVw5fgdfgdgfdgfgfdgfdgfd

Do you know how can I fix it?

You have to use the public key.
