When creating a new map is 'undefined' an not useable...

[HubertusWine]

... and disappears when reloading the page.

I am creating a private map since we are not using corporation and alliance maps. When I create the map it shows up, but when selecting it, the pop-up notification says 'Map loaded: undefined' and when changing settings it's always refereed to as 'undefined'. We managed to create one map that loaded properly, but most of the times it fails.

I can't find any errors in the logs except for '%timestamp INFO reaped unknown pid 18xxx'.

The .env settings are as follows:
PROJECT_ROOT="/root/pathfinder-containers" CONTAINER_NAME="pf" DOMAIN="pathfinder.REDACTED" \# Emails from Let's Encrypt about your certificate will go here LE_EMAIL="REDACTED" APP_PASSWORD="REDACTED" MYSQL_PASSWORD="REDACTED" CCP_SSO_CLIENT_ID="REDACTED" CCP_SSO_SECRET_KEY="REDACTED" CCP_ESI_SCOPES="esi-location.read_online.v1,esi-location.read_location.v1,esi-location.read_ship_type.v1,esi-ui.write_waypoint.v1,esi-ui.open_window.v1,esi-universe.read_structures.v1,esi-corporations.read_corporation_membership.v1,esi-clones.read_clones.v1,esi-characters.read_corporation_roles.v1,esi-search.search_structures.v1"
