Summary
The GenAISemanticProcessor._get_operation_name() returns "unknown" for span data types it doesn't explicitly handle, producing spans named unknown in the trace. The OpenAI Agents SDK's turn span is one such case.
Details
In span_processor.py, _get_operation_name() handles GenerationSpanData, AgentSpanData, FunctionSpanData, ResponseSpanData, TranscriptionSpanData, SpeechSpanData, GuardrailSpanData, and HandoffSpanData — but falls through to return "unknown" for anything else.
The OpenAI Agents SDK emits a turn span (via CustomSpanData) as part of its Agent workflow → invoke_agent → turn → response hierarchy. The distro produces:
Agent workflow → unknown → invoke_agent Assistant → unknown → chat gpt-4o-mini
The base A365 SDK correctly maps these to "chain" operation with the original span name preserved (e.g. turn).
Expected behavior
Unrecognized span data types (including CustomSpanData) should map to a meaningful fallback operation name (e.g. chain) and preserve the original span name from span_data.type, not produce unknown.
