warning for callabike

[ThorstenFroehlinghaus]

The lamassu logs provide the following warnings for callabike:

2026-01-23T08:20:03.650963138Z {"serviceContext":{"service":"lamassu"},"mdc":{"systemId":"callabike"},"message":"Skipping station due to missing station information feed for provider=FeedProvider{systemId='callabike', operatorId='CAB:Operator:callabike', operatorName='Call-A-Bike', codespace='CAB', url='http://apis.deutschebahn.com/db-api-marketplace/apis/shared-mobility-gbfs/v2/de/CallABike/gbfs', language='de', authentication=org.entur.lamassu.model.provider.Authentication@523325cf, excludeFeeds=null, aggregate=true, vehicleTypes=null, pricingPlans=null, version='null', enabled=true} stationId=CAB:Station:927f0a2a-d0a9-3347-8ad3-53b9dde92cfa\n","severity":"WARN","reportLocation":{"filePath":"org.entur.lamassu.leader.entityupdater.StationsUpdater","lineNumber":"226","functionName":"processDeltaUpdate"}}

The warning occurs on Prod and Test. Such stations are skipped by lamassu.

The warning seems to ccour for stations which actually do not provide vehicles - which is a legal situation:

                                           {
                                                           "station_id": "927f0a2a-d0a9-3347-8ad3-53b9dde92cfa",
                                                           "num_bikes_available": 0,
                                                           "vehicle_types_available": [
                                                           ],
                                                           "num_docks_available": 40,
                                                           "is_installed": true,
                                                           "is_renting": true,
                                                           "is_returning": true,
                                                           "last_reported": 1769156798
                                           },

The station is avaible and modelled correctly:

                                                           "station_id": "927f0a2a-d0a9-3347-8ad3-53b9dde92cfa",

                                                           "rental_uris": {
                                                                           "android": "https://www.callabike.de/app",
                                                                           "ios": "https://www.callabike.de/app"
                                                           }
                                           },

As this warning is logged only for a single provider, I'm suspicious if it might be caused by a randomly occurring data issue.
However, we currently don't see any feed validation issues for callabike. Turns out, that even if the feeds infrequently had missing stations in station_information, we would not become aware as there currently exists no such validation.

This is now addressed by MobilityData/gbfs-validator-java#189. After this PR has been merged, a new validator version released and that incorporated in lamassu, we should upgrade lamassu and check if above warning correlates with feed validation issues, which then would proof it's a data issue and not a lamassu bug.

Another observation: there are stations with 0 bikes available which don't cause above warning, so it's not strictly correlated to empty stations.
