Error Handler node
Catches errors from connected nodes so the flow keeps running — fallbacks, alerts and graceful degradation instead of silent failures.
Error Handler (error_handler) watches connected nodes and takes over when they fail: log it, alert someone, run a fallback branch — the run survives.
Configuration
Open the node (double-click) to edit it. Key fields:
- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Watched nodes — which failures it captures.
- Recovery branch — what runs when an error arrives.
Inputs & outputs
It receives the error (message, node, payload) and emits it to its recovery branch. Downstream nodes reference its output with {{node_id.field}} — see the variables reference.
