HVV ferry departures not working.

[fxb]

It seems like HVV ferry departures are not working.

For example id 6256 is the Teufelsbrück stop.

Requesting departures via https://v5.hvv.transport.rest/stops/6256/departures?ferry=true always returns an empty array, while the HVV website lists ferry departures.

I'll check with hafas-client's debugging CLI:

cd hafas-client
./tools/debug-cli/cli.js hvv locations 'Teufelsbrück' | jq

[
    {
        "type": "stop",
        "id": "6256",

        }
    },
    {
        "type": "stop",
        "id": "5822",
        "name": "Teufelsbrück (Fähre)",
        "location": {

            "longitude": 9.863845
        },
        "products": {

            "long-distance-train": false,
            "long-distance-bus": false
        }
    },
    // …
]

./tools/debug-cli/cli.js hvv departures 6256 '{duration: 600}' | jq
# []
./tools/debug-cli/cli.js hvv departures 5822 '{duration: 600}' | jq
# []

TLDR: Yes, it seems like HVV's HAFAS mgate.exe API doesn't return ferries.

Can you check with other ferry lines and at another stop?

[fxb]

I did check some other stops as well, and none seemed to return anything.

Another example that basically only has ferrys stopping is 3598 ("Rüschpark")

I haven't read up on the internal workings of things yet, but could it have something to do with the bitmasks defined in https://github.com/public-transport/hafas-client/blob/master/p/hvv/products.js ?

I reported another issue that just from my gut feeling could also be caused by some mismatch of these bitmasks? See: https://github.com/public-transport/hafas-client/issues/262

[...] could it have something to do with the bitmasks [...] ?

Yes, this is how hafas-client requests departures for specific "products" (basically like categories).

But even without the bitmask in place, thus using the server's default, it doesn't return any departures for the stops 6256 & 5822.
