Relevant stops not included in alerts

[PasiSalenius]

The following alert query returns an alert for tram 7B.

{
  alerts {
    id
    route {
      gtfsId
    }
    stop {
      gtfsId
    }
    alertDescriptionText
  }
}

But even though stops are listed as affected by the disruption alert, the stops property in the graphQL response is empty.

 "id": "QWxlcnQ6NTM3MDUgSFNMIDEwMDdCIHRydWUgMCAgbnVsbCAgIG51bGwg",
 "route": {
   "gtfsId": "HSL:1007B"
 },
 "stop": null,
 "alertDescriptionText": "Raitiolinjat 7A ja 7B poikkeusreitillä klo 16-24, ajetaan Rautatieaseman kautta. Seuraavat pysäkit jäävät ajamatta: Snellmaninkatu, Kansallisarkisto, Hallituskatu, Senaatintori, Aleksanterinkatu ja Ylioppilastalo. Syy: yleisötapahtuma. Lisätietoja: hsl.fi"

Although the GTFS-realtime specification and the Digitransit platform can list affected stops, the source systems at HSL don't yet provide this information in structured format.
