My `log4j2.properties` setup:

```auto
appender.rolling.type = RollingFile
appender.rolling.name = plain_rolling
appender.rolling.fileName = ${sys:ls.logs}/logstash-plain.log
appender.rolling.filePattern = ${sys:ls.logs}/logstash-plain-%d{yyyy-MM-dd}-%i.log.gz
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c]%notEmpty{[%X{pipeline.id}]}%notEmpty{[%X{plugin.id}]} %m%n
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 30
appender.rolling.avoid_pipelined_filter.type = PipelineRoutingFilter

appender.json_rolling.type = RollingFile
appender.json_rolling.name = json_rolling
appender.json_rolling.fileName = ${sys:ls.logs}/logstash-json.log
appender.json_rolling.filePattern = ${sys:ls.logs}/logstash-json-%d{yyyy-MM-dd}-%i.log.gz
appender.json_rolling.policies.type = Policies
appender.json_rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.json_rolling.policies.time.interval = 1
appender.json_rolling.policies.time.modulate = true
appender.json_rolling.layout.type = JSONLayout
appender.json_rolling.layout.compact = true
appender.json_rolling.layout.eventEol = true
appender.json_rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.json_rolling.policies.size.size = 100MB
appender.json_rolling.strategy.type = DefaultRolloverStrategy
appender.json_rolling.strategy.max = 30
appender.json_rolling.avoid_pipelined_filter.type = PipelineRoutingFilter

```

`logstash-plain.log` is ok, but `logstash-json.log` is empty.

How to get logs in the file in json?

Thank you in advance.
