Skipping further processing. 22:49:33,673 |-ERROR in ch.qos.logback.classic.AsyncAppender[STDOUT-ASYNC] - No attached appenders found. {code} To get it to work, I have to switch to the "appender-ref" style. {code:java} <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="com.zendesk.logging.JsonLogEncoder"/> </appender> <appender name="STDOUT-ASYNC" class="ch.qos.logback.classic.AsyncAppender"> <appender-ref ref="STDOUT" /> </appender> <root level="${ROOT_LOG_LEVEL:-info}"> <appender-ref ref="STDOUT-ASYNC"/> </root> </configuration> {code} Not sure if this an intentional change to drop support for the format we used earlier, or a bug.
