MESSAGE_TOO_LARGE in MirrorMaker2

[bingkunyangvungle]

I was trying to use MM2 to sync data between Kafka, but got error:
2025-09-05 03:18:04 WARN [kafka-producer-network-thread | connector-producer-mm2-source->mm2-target.MirrorSourceConnector-3] Sender:672 - [Producer clientId=connector-producer-mm2-source->mm2-target.MirrorSourceConnector-3] Got error produce response in correlation id 2077 on topic-partition topic, splitting and retrying (2147483647 attempts left). Error: MESSAGE_TOO_LARGE

I actually checked the msg in the original cluster and manually sent on by one and it has no issue of syncing to the target cluster.
Could someone help to identify what cause this issue?

Here is the config:
