i think it has to be something with the properties File, but i am really not sure if i didnt made some mistakes with the migration:

old log4j 1.x:

You're missing some configurations in your log4j2 properties. You created RollingFile appenders, however you didn't define how they should roll. That's why the errors are telling you that filePattern and policy are null. Note that the DailyRollingFileAppender class no longer exists in log4j2, so you have to basically set it up yourself.

The filePattern property tells you how to name the file when you roll it. For example, if you wanted the rolled files to contain the date, you could do something like

appender.default.filePattern=../var/first-server-%d{yyyyMMdd}.log

which would give you a name like first-server-20201017.log.

You also need to set up the policies to describe when to roll. In your case it looks like you want daily rolling, so it would be something like

appender.default.policies.type = Policies
appender.default.policies.time.type = TimeBasedTriggeringPolicy
appender.default.policies.time.interval = 1
appender.default.policies.time.modulate = true

This page gives a lot more details about configuring log4j2.
