Additional information

Please note I replaced the actually used Start & Target Location in the log output above by "StartLocation" and "TargetLocation".

Additionally found in HA log:

Unfortunatly I am unable to reproduce it with the trains I am using. Could you please try removing the trains and then set them up again from the deutschebahn HA ui?

Could you please try removing the trains and then set them up again from the deutschebahn HA ui?

That's what I did first (same start / stop combination) before creating this issue.

Interestingly, it magically healed itself around 3rd of september (02:36 in the night) without any action or correlation (no HA Core restart, no integration reload etc.):

Especially because of this I was hoping the log output itself would at least allow to say "it's a local issue in the integration" or "it's an API issue, Deutsche Bahn simply did not provide the requested data". Otherwise, this might happen at any time again...
