Egress Request (sanitised)

{
  "roomName": "49b68608-a21b-4948-ac20-a2e2a749dff9",
  "layout": "single-speaker",
  "fileOutputs": [
    {
      "fileType": "MP4",
      "filepath": "<redacted>/2025-08-08/20-22-05_49b68608-a21b-4948-ac20-a2e2a749dff9.mp4",

        "accountKey": "<redacted>",
        "containerName": "recordings"
      }
    }
  ]
}

Additional Context

Provider: Azure Blob

Container name ("recordings") is present in the request but missing from the returned URLs.

manifestLocation shows the same omission.
