This topic has multiple produce, some messages cannot be processed, I checked the schema id 13212 and it looks fine. Most of the messages are being consumed normally.

## the exception information is as follows

2024-05-09 10:03:31.702 ERROR [main] - [SchemaConsumerTest.java:100] - Error deserializing key/value for partition xxxx.topic-3 at offset 480960. If needed, please seek past the record to continue consumption.
