Example [#example]

A minimal configuration for this block:

```json
{
  "type": "trigger/rss",
  "config": {
    "feedUrl": "<PreviousStep.field>",

Limits and failure modes [#limits-and-failure-modes]

* Required fields (`feedUrl`, `pollingInterval`) must be set, or the block fails validation before it runs.
