Intermittent Maximum Recursion Depth Reached Error

[jaineshp]

Behavior

1. Noticing Maximum Recursion Depth Reached Error intermittently for calls longer than ~1.5 mins
2. After 1-1.5 mins: Bot stops speaking, and after I disconnect the call I get the following trace (attached below)

Seeing this error recently, had made following changes:

1. Moved to Version 57
2. Added Sentry SDK
3. Enabled Metrics (enable_metrics=True, enable_usage_metrics=True, report_only_initial_ttfb=False)
4. Added STT Mute Filter Strategy

Setup:
Using a simple pipeline for Outbound Calling (Deepgram + OpenAI + 11Labs)

pipeline = Pipeline([
        transport.input(),  # Websocket input from client
        user_idle,  # Idle user check-in
        stt_mute_processor,  # Add mute processor before STT
        stt,  # Speech-To-Text
        transcript.user(),  # User transcripts
        context_aggregator.user(),
        llm,  # LLM
        tts,  # Text-To-Speech
        transport.output(),  # Transport bot output
        transcript.assistant(),  # Assistant transcripts
        context_aggregator.assistant(),  # Assistant spoken responses
    ])
