🐛 Bug Report: Missing `throttled` property when using throttle step via bridge

[lqmanh]

📜 Description

In Novu dashboard, it shows this error:

{
  "url": "...",
  "statusCode": 400,
  "message": "Workflow with id: `direct-message` has an invalid state. Step with id: `throttle-step` has invalid result. Please provide the correct step result.",
  "code": "ExecutionStateResultInvalidError",
  "data": [
    {
      "path": "",
      "message": "must have required property 'throttled'"
    }
  ],
  "cause": {
    "name": "HTTPError",
    "code": "ERR_NON_2XX_3XX_RESPONSE",
    "timings": {
      ...
    }
  }
}

👟 Reproduction steps

1. Set up code-based workflows with Novu framework as normal
2. Set up bridge endpoint as normal
3. Writing something like this in a workflow:

await step.throttle('throttle-step', async () => ({
    type: 'fixed',
    amount: 15,
    unit: 'minutes',
    threshold: 1,
    throttleKey: payload.conversationId,
  }));
