Not able to read binlog properly from mariadb 10.1 using debezium mysql connector

We are using mariadb10.1 and trying to fetch binlog for both DDL and DML query  using debezium mysql connector.

but we are facing issue in reading those.

 

Currently we are getting :

For DML query we are getting

{
  "source" :

{     "server" : "mysql-db01"   }

,
  "position" :

{     "transaction_id" : null,     "ts_sec" : 1638209309,     "file" : "mysql-bin.000003",     "pos" : 773,     "server_id" : 136,     "event" : 1   }

,
  "databaseName" : "",
  "ddl" : "# Dummy event re",
  "tableChanges" : [ ]
}

 

Need help how can we fetch  proper data and in correct format as mentioned in debezium documentation both for DDL as well as DML.
