I'm also getting this error, but I don't have access to the server console to get the full message. (its on a public server I'm not an admin of). It happens for me every time in the server, no matter the stations. But I can't get it to happen in another (signleplayer) world. Same "Cannot invoke "java.util.Set.stream()" because the return value of "java.util.Map.get(Object)" is null"

Version 1.20.1 fabric-0.15.11 mod version 0.5.2-beta-fabric

Lots of other mods, but since OP didn't include a modlist its probably not an incompatibility? I can send a modlist if needed.

Solved after the last update. However as I observed, the source of the problem was existance of one train. When I exclude that train , it was all okay.

Edit 1: Oh and yeah I should have shared the modlist, sorry. Although, since it is all okay after update with more mods on my server before, I don't think it is an incompatibility problem.
