Steps to reproduce

  1. Use Nextcloud FPM docker container image
  2. Configure 'logfile' => '/dev/stdout',
  3. Open Log in administrator settings, see empty log and HTTP Status 500 for apps/logreader/api/poll?lastReqId= request in browser console

Expected behaviour

Log should be filled with log entries

Actual behaviour

Log stays empty and i see this in docker logs:

After opening this issue i found the solution myself.

Thanks to this comment nextcloud/docker#2119 (comment) i found this in the Nextcloud administrator manual: https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/config_sample_php_parameters.html#log-type:

I needed to change the Nextcloud config log settings to:

  'log_type' => 'file',
  'logfile' => 'syslog',

Now the log is inside the container and in Nextcloud logreader.

Closing this issue.
