Prevent Concurrent Workflow Runs Using Redis

What does this template do? This workflow sets a small "lock" value in Redis so that only one copy of a long job can run at the same time. If another trigger fires while the job is still busy, the workflow sees the lock, stops early, and throws a clear error. This protects your data and keeps you from hitting rate limits.

Use Case Great when the same workflow can be called many times in parallel (for example by webhooks, cron jobs, or nested Execute Workflow calls) and you need an "only run once at a time" guarantee without bui

Help me set up the n8n workflow "Prevent Concurrent Workflow Runs Using Redis" (https://n8n.io/workflows/3976). It uses: Redis. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
