Standalone sim won't work on edited infra - unknown error

[axrolld]

What happened?

I fixed a hole in Narbonne train station by adding a track link here

The pathfinding works until Sète where there's another hole

But the standalone simulation won't work, with this error message :

And this in console:
{ "status": 500, "type": "assert_error", "context": { "message": "Assertion failed", "stack_trace": [ "ScheduleMetadataExtractor.kt:65", "ScheduleMetadataExtractor.kt:84", "StandaloneSim.java:94", "StandaloneSim.java:148", "StandaloneSimulationEndpoint.java:69", "FkRegex.java:153", "FkRegex.java:217", "FkChain.java:72", "TkFork.java:98", "TkFallback.java:84", "TkFallback.java:66", "TkWrap.java:58", "TkSlf4j.java:110", "BkBasic.java:123", "BkBasic.java:99", "BkSafe.java:46", "BkWrap.java:51", "BkParallel.java:81", "ThreadPoolExecutor.java:1136", "ThreadPoolExecutor.java:635", "Thread.java:833" ], "url": "http://staging-core-service.osrd-team-staging.svc.cluster.local:8000/standalone_simulation" }, "message": "assert check failed" }

What did you expect to happen?

No response

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

1. Go to my scenario and try to run a train over this track in Narbonne
