[bloussou]

What happened?

The following error is happening sometimes on BASIC timetables:

{"status":500,"type":"core:assert_error","context":{"url":"http://osrd-rec-core.osd-rec01.svc.cluster.local/v2/standalone_simulation","file_location":"AbstractAllowanceWithRanges.java:137","assert_message":"Discontinuity on the edges of the allowance region","stack_trace":["AbstractAllowanceWithRanges.java:137","StandaloneSimulation.kt:259","StandaloneSimulation.kt:102","SimulationEndpoint.kt:56","FkRegex.java:153","FkRegex.java:217","FkChain.java:72","TkFork.java:98","TkDataDog.kt:27","TkDataDog.kt:16","TkDataDog.kt:15","TkWrap.java:58","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:1144","ThreadPoolExecutor.java:642","Thread.java:1583"]},"message":"assert check failed"}

What did you expect to happen?

Have a "normal" error. This is blocking scenario opening.

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

• Open a BASIC timetable and look for the network in the navigator : https://rec-osrd.reseau.sncf.fr/operational-studies/projects/4/studies/50/scenarios/131

• Or locally, using the last dump on France infra, and provide the given payload (provided aside) to http://localhost:4000/api/v2/timetable/<scenario>/train_schedule/

What operating system, browser and environment are you using?

• Browser: Firefox
