Publish
Publishes in RabbitMQ.
This node is also exposed as an AI Agent tool.
This node has 1 input port and 1 output port.
Common Properties
Every node shares these.
- Name — the node's display name on the canvas.
- Color — the node's colour on the canvas.
- Delay Before (sec) — wait this long before the node runs.
- Delay After (sec) — wait this long after the node runs.
- Continue On Error — carry on instead of failing the flow. Defaults to false.
info
When Continue On Error is true the error is not raised at all, so a Catch node will not see it either.
