Http errors are not sent to the stream as errors?

[Terranic]

Hi all,

I´m currently encounting 429 http errors on the openai chatcompletion API,- today it is good test the apps robustness. However, I encounter a problem with the openai dart package, because I´m not getting notified about the 429 error... the stream simply never closes. The app hangs. Is there no support for errors right now? The "Error" print is never reached

Error in browser console:

Stream<String> callAI(String systemprompt, String prompt,
      {required double temperature, required int maxtokens}) async* {
    var chatStream = OpenAI.instance.chat.createStream(
        model: "gpt-4-1106-preview",
        maxTokens: maxtokens,
        temperature: temperature,
        messages: [
          OpenAIChatCompletionChoiceMessageModel(
              role: OpenAIChatMessageRole.system,
              content: [
                OpenAIChatCompletionChoiceMessageContentItemModel.text(
                    systemprompt)
              ]),
          OpenAIChatCompletionChoiceMessageModel(
              role: OpenAIChatMessageRole.user,
              content: [
                OpenAIChatCompletionChoiceMessageContentItemModel.text(prompt)
              ]),
        ]);

    String res = "";

    chatStream.handleError((onError) => print("ERROR $onError"));

    await for (var token in chatStream) {
      String tok = token.choices.first.delta.content?.first.text ?? "";
      res += tok;
      yield res;
    }
    yield res;
  }

stream methods now should allow you to catch errors in the onError function callback of your stream subscription.
