Workarounds

n8n workflow with OpenAI model traced in Langfuse

@rorubyy has created a n8n node for that wraps OpenAI models and sends tracing data to Langfuse. You can find it here: rorubyy/n8n-nodes-openai-langfuse

Alternatively, @rwb-truelime has developed n8n-langfuse-shipper, a Python project that ships n8n execution data to Langfuse using the OTEL (OpenTelemetry) API. This approach provides a broader integration by capturing workflow execution data from n8n and forwarding it to Langfuse for observability and tracing.
