Division by zero at PhotofilesService.php

Hello,

i installed Maps and start to sync my Photos and tracks, It works good. But my System slow down and i get this Error message.

My System:

  1. Nextcloud 17.0.0
  2. Ubuntu 16.04.3 LTS
  3. Nginx
  4. RAM: 15,6 GB
  5. Intel® Core™ i7-2600 CPU @ 3.40GHz

[PHP] Error: Division by zero at /var/www/html/custom_apps/maps/lib/Service/PhotofilesService.php#420

The Second Question is, how can i Setup Navigation completly? I running an OSRM Backend Server with Docker, also i enter the API Key for MAPBOX.

No route planning engine is specified in the advanced Nextcloud settings. Route planning is deactivated for the user.

i Setup the OSRM Backend Server with this Tutorial https://github.com/cartography/osrm-backend-docker and this works fine. Tested with the Frontend-Server.
