📄 Description

Description

Fixes #19840 - RedisCluster publish fails on POST /api/tasks/stop/{task_id}

Added

N/A

Changed

Added RedisCluster support in redis_send_command() function

Deprecated

N/A

Removed

N/A

Fixed

RedisCluster pub/sub: Fixed AttributeError when using Redis Cluster for task commands
Previously, redis.publish() method doesn't exist on RedisCluster objects
Now the code:
1. Checks if redis object is a RedisCluster instance
2. For RedisCluster: iterates through all master nodes and publishes to each
3. For standard Redis: uses publish() normally
This ensures task stop commands reach all worker nodes in cluster deployments

Security

Issue: [GH-ISSUE #22909] feat: Native Azure DevOps Repos (Git) integration as a Knowledge Base source for RAG (#19840)
Enables proper task cancellation in multi-node deployments using Redis Cluster
