ERROR Unable to process event: 'java.time.Instant ch.qos.logback.classic.spi.ILoggingEvent.getInstant()'

I tried to use logstash-logback-encoder with spring boot for sending logs to the ELK. but unfortunately I get this error.

can I have a solution please.

logstash-logback-encoder >= 7.4 requires logback >= 1.3

Therefore, you have two options to solve your problem:

A. Continue using logstash-logback-encoder >= 7.4, and upgrade logback >= 1.3

OR

B. Downgrade logstash-logback-encoder to 7.3 (which supports logback 1.2), and continue using logback 1.2.
