HELP! Logstash restarting after ip2location plugin update

I had an issue with logstash restarting so I updated ip2location plugin and now it keeps restarting every 15 seconds. The error before was ConcurrentModificationException: null.
I use logstash v 7.4.2 and the plugin version is 2.1.4

Another issue is that it does not write logs to /var/log/logstash now :frowning:

Run, on the command line, the command that the service manager uses to start logstash and see what it logs.

I have run it using these 2 commands but got no result and besides, now it does not even write to log file (/usr/share/logstash/logstash-plain.log) anymore:

/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d 
service logstash restart

I have checked directory permissions and also /etc/systemd/system/logstash.service
It keeps restarting

You will need to run it as the user that systemd uses, and you will need to start it using the command shown in /etc/systemd/system/logstash.service. Also, if the EnvironmentFile entries set anything of significance you will need those variables set.

I have tested it with that user. and I had provided --path.settings as well
