Fixed critical bug: PubSubMsg contains channel in msg.channel, not context.channel - Updated callback signature to correctly extract message and channel from PubSubMsg - Removed debug logging from adapters and test configuration - Added error handling in closePubSubPair to ignore already-closed connections - All 321 tests now passing (100% success rate) - Full compatibility achieved for both ioredis and valkey-glide clients Breaking down the fix: 1. PubSubMsg structure: { message: GlideString, channel: GlideString, pattern?: GlideString } 2. Callback receives msg directly, not msg + context 3. Extract channel: convertToString(msg.channel) 4. Extract message: convertToString(msg.message) 5.
