    "info": "# Auto-resume on workflow failure\n\nThis example demonstrates how to automatically resume a failed workflow using a **simple loop pattern**. When a workflow fails, it loops directly back to the launch node which automatically retries with resume enabled.\n\n## How it works (Loop Pattern)\n\n1. **Trigger** - Click inject to start (or use any trigger)\n2. **Launch** - Launches workflow (reads workflow ID from msg.workflowId for resume)\n3. **Monitor** - Monitors workflow status with three outputs\n4. **On Success** - Flow completes (output 2)\n5. **On Failure** - Loops directly back to Launch node (output 3)\n\n## Key Features\n\n- **Single Launch Node**: The same node handles both initial launch and resume\n- **Direct Loop**: Failed workflows loop directly back - no intermediate nodes needed!\n- **Automatic resume**: The launch node reads msg.workflowId and automatically:\n  - Fetches the session ID from the failed workflow\n  - Enables Nextflow resume\n  - Uses the correct commit/revision\n\n## Setup Instructions\n\n1. Double click the **\"Launch workflow\"** node:\n   - Configure Seqera Platform credentials\n   - Set launchpad name\n   - **Important**: \"Resume from\" field is set to read from \"msg.workflowId\" (type: msg)\n\n2. Configure the **\"Monitor workflow\"** node with same Seqera config\n\n3. Click **\"Deploy\"** in Node-RED (top right)\n\n4. Click the **Inject** node to start\n\n## Important Notes\n\n- The resumed workflow must use the same work directory as the original\n- Your compute environment must have access to the cached results\n- **This creates an infinite loop** that retries until success - add retry limit logic if needed\n- Each retry uses Nextflow's `-resume` to skip completed tasks",
