Where does the logs in Flink GUI's Exception tab come from?

[Averell]

Hi everyone,

I am running Flink in EMR YARN cluster, and when the job failed and
restarted, I could see some logs in the Exception tab of Flink GUI.

I could not find this piece of logs on my cluster's hard-disk - not in TM or
JM logs.

Where can I find this?

Thanks.

Here below is my logback.xml. I'm not sure it has anything to do with my
question.

<configuration>
    <appender name="file" class="ch.qos.logback.core.FileAppender">
        <file>${log.file}</file>
        <append>false</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level
%logger{60} %X{sourceThread} - %msg%n</pattern>
        </encoder>
    </appender>
    
    <root level="WARN">
