I think it's not missed. The SLF4J logger supports adding an exception argument at the tail.

You can try the following code directly:

@Slf4j
public class Main {

    public static void main(String[] args) {
        final var e = new RuntimeException("error");
        log.info("exception: ", e);
    }
}

and you will see the output:

[2023-07-21 13:20:37,967] mainid INFO exception:  (org.example.Main)
java.lang.RuntimeException: error
	at org.example.Main.main(Main.java:9)

thanks for the reply. I'll close this issue

by the way, if the bulk request doesn't show the detailed / root cause of the exception, how is the user supposed to debug the error?
