What did you expect to happen?

No error

How can we reproduce it (as minimally and precisely as possible)?

1. create an empty scenario with TSv2
2. try a STDCM path like :

Error context is

    override fun getTrackChunkZone(chunk: TrackChunkId): ZoneId {
        return chunkToZoneMap[chunk]!!
    }

Meaning that a chunk does not have a zone. That is weird.

I can't reproduce locally, with the exact same parameter on the exact same commit :thinking:

Was the infra edited in any way?

[bloussou]

Nope the infra is not edited

[eckter]

Can easily be reproduced by just iterating over the chunks and checking whether they have a matching zone

            for (track in infra.rawInfra.trackSections) {
                for (chunk in infra.rawInfra.getTrackSectionChunks(track)) {
                    val tmp = infra.rawInfra.getTrackChunkZone(chunk)
                    println(tmp)
                }
            }

Sur l'infra France, on a 2465 chunks sans zones :D Je vais essayer de voir pk, mais c'est drôle en tout cas.
