If these notes still leave you facing a problem, reach out to us on Gitter where we will happily assist you.

Server logs

Server logs show all sort of warnings and errors and should be your first stop while troubleshooting problems with Reconmap. Its location is /var/log/nginx/error.log inside the backend API Docker container.

If you want to see the last lines of this file run the following Docker command:

$ docker exec reconmap-backend-api tail /var/log/nginx/error.log

Example output:

#0 /var/www/webapp/src/Services/ConfigLoader.php(12): json_decode()
#1 /var/www/webapp/public/index.php(26): Reconmap\Services\ConfigLoader->loadFromFile()
#2 {main}
