Debezium stops after inserted or update data into the table when using decoderbufs

Question

The initial synchronization worked as expected, but when I insert or update data into the table, the connection with postgres closes.The connector is still marked as active and running.This issue only occurs when the logical decoding plugin used is decoderbufs, and it runs normally when using pgoutput.

Datebase:Database: Postgresql-12

connector config:

{
  "name": "postgres-connector",
  "config": {
    "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
    "database.hostname": "",
    "database.port": "5432",
    "database.user": "postgres",
    "database.password": "123456",
    "database.dbname" : "postgres",
    "topic.prefix": "postgres_service",
    "table.include.list": "debezium.index_example,debezium.stock_example",
    "decimal.handling.mode": "string"
  }
}
