[smoke-detector] 🚨 CRITICAL: GenAIScript Failure Persists After Model Fix - 7th Consecutive Failure (API Key or Service Issue)

[github-actions]

🚨 CRITICAL RECURRING FAILURE - 7th Consecutive Occurrence

Summary

The Smoke GenAIScript workflow has FAILED AGAIN with the EXACT SAME ERROR, despite the model configuration being fixed from gpt-4.1 to gpt-4o in previous investigations. This is the 7th consecutive failure since 2025-10-22. The pattern has EVOLVED - the model name is now correct, but the error persists, pointing to a different root cause.

Failure Details

• Run: #18771194604
• Commit: 4fcfdc4 - "Add support for silently ignoring description and applyTo fields in frontmatter (Add support for silently ignoring description and applyTo fields in frontmatter #2266)"
• Trigger: schedule (automated smoke test)
• Duration: 3.1 minutes
• Failed Job: detection (59 seconds)
• Status: ❌ FAILED

Root Cause Analysis - Pattern Evolution

🔄 Pattern Has Changed

Previous Issues (#2157, #2204, #2207, #2227): Invalid model name openai:gpt-4.1
Current Configuration: ✅ Valid model name openai:gpt-4o (confirmed in .github/workflows/shared/genaiscript.md:6)
Result: ❌ Same error persists

This definitively rules out model configuration as the root cause. The failure has evolved from a configuration issue to what appears to be an authentication, service availability, or code bug issue.

Error Chain (Unchanged Despite Fix)

1. GenAIScript attempts to use model openai:gpt-4o (valid model) ✅
2. OPENAI_API_KEY validation passes ✅
3. GenAIScript calls OpenAI API ❓
4. Something fails - API returns error/null/unexpected response ❌
5. GenAIScript crashes: TypeError: Cannot read properties of undefined (reading 'text') ❌
6. Detection job fails with exit code 255 ❌

Investigation Findings

Possible Root Causes (Now That Config Is Fixed)

1. Invalid/Expired OPENAI_API_KEY 🔴 MOST LIKELY

   • The secret may exist but be invalid/expired
   • API returning 401/403 authentication errors
   • GenAIScript doesn't properly handle auth failures

2. OpenAI API Service Issues 🟡 POSSIBLE

   • Rate limiting (429 errors)
   • Service degradation or outages
   • Timeout issues

3. GenAIScript Bug 🟡 POSSIBLE

   • Poor error handling in githubActionSetOutputs
   • Doesn't check for undefined before accessing .text
   • Mishandles certain API error responses

4. MCP Configuration Issue 🟢 UNLIKELY (but noted)

   Failed to load MCP configuration: MCP configuration file not found: /tmp/gh-aw/mcp-config/mcp-servers.json
   

   This is a separate warning - MCP config is optional for this workflow

Configuration Status ✅

# .github/workflows/shared/genaiscript.md:6
GH_AW_AGENT_MODEL_VERSION: "openai:gpt-4o"  ✅ CORRECT

The model configuration was successfully updated and is now valid. The workflow also includes:

• ✅ API key validation step (passes)
• ✅ GenAIScript version 2.5.1 installed
• ✅ Proper environment variable setup

Failed Jobs and Errors

Job Execution Summary

1. ✅ activation - succeeded (2s)
2. ✅ agent - succeeded (1.4m) - Agent completed successfully
3. ❌ detection - FAILED (59s) - Threat detection crashed
4. ✅ create_issue - succeeded (3s)
5. ⏭️ missing_tool - skipped

Pattern: Failing every ~6 hours on scheduled runs
Duration: Over 34 hours of continuous failures
Failure Rate: 100% since first occurrence
Model Fix: Occurred between run #5 and #6, but failures continued

Recommended Actions

🔴 CRITICAL - Immediate Investigation

• Verify OPENAI_API_KEY secret in repository settings

  • Check if the key exists
  • Test the key manually with a simple OpenAI API call
  • Rotate key if invalid/expired
  • Ensure proper permissions are set

• Check OpenAI API Status

  • Visit (redacted)
  • Check for service degradation or outages
  • Review any rate limiting or quota issues

• Enable Detailed Logging

  • Capture actual OpenAI API responses
  • Log HTTP status codes and error messages
  • Add verbose debugging to GenAIScript execution

🟡 HIGH PRIORITY - GenAIScript Error Handling

• File upstream bug with GenAIScript

  • Repository: https://github.com/microsoft/genaiscript
  • Issue: githubActionSetOutputs doesn't handle undefined results
  • Request: Add null checks before accessing .text property
  • Request: Better error messages for API failures

• Add Retry Logic

  • Implement exponential backoff for transient failures
  • Add circuit breaker pattern for persistent failures

🟢 MEDIUM PRIORITY - Alternative Solutions

• Consider switching providers

  • Option A: GitHub Models (github:gpt-4o)
  • Option B: Azure OpenAI (if configured)
  • Option C: Disable threat detection until issue resolved

• Add Health Check

  • Pre-flight API key validation with test call
  • Fail fast with clear error message
  • Skip smoke test if API unavailable

🔵 LOW PRIORITY - Documentation

• Update troubleshooting guide with API key validation steps
• Document OpenAI API dependency and alternatives
• Add monitoring for API key expiration

Prevention Strategies

1. Implement API Key Health Checks - Test API keys before workflows run
2. Better Error Handling - Fix GenAIScript to handle API failures gracefully
3. Monitoring & Alerts - Monitor OpenAI API status and API key validity
4. Retry Logic - Add exponential backoff for transient API failures
5. Provider Alternatives - Configure fallback AI providers
6. Scheduled Key Rotation - Proactively rotate API keys before expiration

Impact Assessment

Severity: 🔴 CRITICAL

• All GenAIScript smoke tests failing continuously for 34+ hours
• Threat detection non-functional
• 7 consecutive failures with no resolution
• Model fix applied but issue persists
• Pattern evolution indicates deeper systemic issue

Urgency: 🔴 IMMEDIATE

• Issue extends beyond configuration to authentication/service layer
• Requires investigation of API key validity
• May require provider change if OpenAI unreliable

Scope:

• Affects: All workflows using GenAIScript with OpenAI
• Frequency: Every scheduled smoke test run (~6 hours)
• Duration: Ongoing since 2025-10-22 19:45 UTC (34+ hours)
• Wasted CI Minutes: ~24.5 minutes (7 failures x 3.5 min average)

Next Steps

This issue requires immediate attention from someone with access to:

1. Repository secrets (to verify OPENAI_API_KEY)
2. OpenAI account/billing (to check API key status)
3. Alternative AI provider configuration

The model configuration has been fixed, but failures persist. This is now an authentication, service, or code bug issue - not a configuration issue.
