majiayu000 Beam Debug Issue Tasks
Debug failed Beam.ai tasks using Langfuse traces.
When to Use
- Diagnose why a task failed, stopped, or needs input
- Find root cause from Langfuse trace reasoning
- Generate debug reports for documentation or handoff
Prerequisites
.env file at project root:
# Beam.ai - BID instance
BEAM_API_KEY=your_bid_api_key
BEAM_WORKSPACE_ID=your_bid_workspace_id
# Beam.ai - Prod instance
BEAM_API_KEY_PROD=your_prod_api_key
BEAM_WORKSPACE_ID_PROD=your_prod_workspace_id
# Langfuse (self-hosted)
LANGFUSE_PUBLIC_KEY=pk-lf-...
LANGFUSE_SECRET_KEY=sk-lf-...
LANGFUSE_HOST=https://tracing.beamstudio.ai
Dependencies: pip install requests python-dotenv
Quick Start
# List issue tasks (default: last 1 day, BID workspace)
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id>
# Debug specific task with full trace analysis
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id> --task-id <task_id>
# Use prod workspace
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id> --workspace prod

Example Output
Debug Report (Smart Brevity)
# Task stopped: condition failed
Checklist evaluation: subfolder must equal 'Schreiben Schuldner' but was null.
**Why it matters**: This task did not complete successfully and may need attention.
**The details**:
- **Status**: `STOPPED`
- **Task**: `ab3cbbb8-28da-41aa-b726-25931d14d7d4`
- **Latency**: 159.6s
- **Cost**: $0.1043
**Key spans**:
- NodeSelection:EdgeEvaluation/v1 (23.4s)
- TaskSuccessCriteriaCheck/v1 (7.2s)
**Root cause**:
> The criterion is not met because subfolder is not set to required value.
**Fix**: Review the condition that stopped execution. Check if input data meets requirements.
