#Investigation

I've checked the verificationHistory of the latest promoted Freight in the Stage status:

"verificationHistory": [
   {
      "finishTime": "2025-05-21T10:28:48Z",
      "phase": "Successful",
      "startTime": "2025-05-21T10:28:48Z"
    }
]

It is created here and doesn't contain ID field.
