Database server crashes when syncing with Komoot

[pdl-nt]

What happened?

OS: Debian Trixie
Wanderer Version: 0.18.3 (Docker)
When syncing with Komoot the database server crashes under specific conditions:
My Komoot account contains 24 planned routes and 196 completed routes. Syncing the 24 planned routes selectively works fine. The completed routes are not synced. The database server restarts with this logs:

I have installed Wanderer on two different machines (the second: Ubuntu 24.04) with the same results. I have testet v0.18.3 (latest) and, additionally, 0.18.1, 0.18.0 and 0.17.2. The results are the same.

Maybe it is a bug or an issue with my configuration or installation.

Version

v0.18.3 and older

I think trails.tchncs.de is also affected as users report problems with their Komoot imports not working:

Line 4 and 5 show an authentication issue, which is not seen in my log. Since sync of planned tours is successful and only sync of completed tours results in this error, there is no authentication failure in my case.
Hint: I had problems with my password. Some special characters like $ in the password resulted in authentication failures.

yes, but thats just strava (and likely my fault because i have rotated my client secret) - however i have added this context just in case
