Bug: Permission check and OpenRouter 404 errors

[mrjcleaver]

Problem 1: Permission Check Error

When a user without permissions tries to use /summarize, the bot crashes with:

discord.errors.InteractionResponded: This interaction has already been responded to before

Root Cause

The permission check at summarize.py:295 was using interaction.response.send_message() AFTER the interaction was already deferred in commands.py:79.

Fix

Changed to interaction.followup.send() which is the correct method to use after deferral.

Problem 2: OpenRouter 404 Errors

Continuous 404 errors in logs from OpenRouter API:

HTTP Request: POST https://openrouter.ai/api/v1/messages "HTTP/1.1 404 Not Found"

Root Cause

The code wasn't explicitly handling anthropic.NotFoundError, so it was being caught by the generic exception handler without proper logging or context.

Fix

Added explicit NotFoundError exception handler that:

• Logs the full error message and request details
• Raises ModelUnavailableError with context
• Will help diagnose the actual OpenRouter issue once deployed

Resolution

Fixed in commit 8675b1b and deployed as v40.

Related Issues

This is the third occurrence of the interaction lifecycle bug:

• Bug: Interaction deferral error in cross-channel permission checks #6 - First discovery in cross-channel error handling
• Bug: v35 used wrong method for deferred interactions #7 - v35 used wrong method after deferral
• This issue - Same bug in permission check code path

Next Steps

Monitor logs after deployment to see the actual NotFoundError details and determine why OpenRouter is returning 404.

OpenRouter Error Identified

The NotFoundError logging revealed the actual problem:

Error code: 404 - {'error': {'message': 'No allowed providers are available for the selected model.', 'code': 404}}
Request was for model: anthropic/claude-3.5-sonnet, base_url: https://openrouter.ai/api

This is NOT a code bug. The error message "No allowed providers are available for the selected model" indicates an OpenRouter account issue:

1. No credits - OpenRouter account may be out of credits
2. Model access not enabled - Account hasn't enabled Claude model access
3. API key configuration - API key may not have permissions for Anthropic models

Action Required

Check OpenRouter dashboard:

• Account credit balance
• Enabled models/providers
• API key permissions

Code Status

The permission check bug (Problem 1) is fixed in v40. The OpenRouter 404s are an account/billing issue, not a code issue.
