Can't see the workflow trace

[eric-easyhealth]

I'm using Haystack2 with latest trackloop 0.26.4, followed the offical guidance to init the traceloop by following code:

Traceloop.init(app_name="app_name", api_key="apikey")

it works perfect and shown me the openai track as following, but how can i enable the workflow track like what is suggested in the quick start document?
PS: i'm using a pipeline in a python class, dummy code as below:

from haystack import Pipeline
from haystack.components.generators.chat import OpenAIChatGenerator

class ChatPipelineViaRAG:
    def __init__(self, api_key:str = '')
        self.retrieve_pipeline = Pipeline()
        self.generator = OpenAIChatGenerator()
        ......
    
    def run(self, messages: List[ChatMessage]) -> dict[str, Any]:
        retrieved_documents = self.retrieve_pipeline.run(parameters...)
        self.messages = process_documents(messages, retrieved_documents)
        return self.generator.run(self.messages)

Thanks @eric-easyhealth! that seems to be a bug with Haystack, do you mind converting this to an issue in the repo? We'll take a look into this
