What Debezium connector do you use and what version?

debezium-jdbc , version:3.0.0.Final

What is the connector configuration?

this is my sink connector configuration, i used  docker to  build the debezium, and this target db in virtual machine:
{
    "connector.class": "io.debezium.connector.jdbc.JdbcSinkConnector",
    "hibernate.connection.driver_class": "oracle.jdbc.OracleDriver",
    "table.name.format": "${source.table}",
    "hibernate.database.type": "oracle",
    "connection.password": "xtreamuser",
    "primary.key.mode": "record_key",
    "hibernate.default_catalog": "XTREAMUSER",
    "tasks.max": "1",
    "batch.size": "1000",
    "hibernate.dialect": "org.hibernate.dialect.OracleDialect",
    "connection.username": "xtreamuser",
    "connection.provider": "com.olm.debezium.DynamicConnectionProvider",
    "hibernate.driver.version": "oracle-12c",
    "topics": "olm_cdc_test.cdc.mysql_source_type_demo",
    "collection.name.format": "${source.table}",
    "hibernate.connection.url": "jdbc:oracle:thin:@192.168.238.138:1521:ORCL",
    "delete.enabled": "true",
    "schema.evolution": "basic",
    "name": "test-hasPk-sink",
    "connection.url": "jdbc:oracle:thin:@192.168.238.138:1521:ORCL",
    "hibernate.schema": "XTREAMUSER",
    "insert.mode": "upsert"
}

What is the captured database version and mode of deployment?

(E.g. on-premises, with a specific cloud provider, etc.)

the source database :  mysql

the source databse  version: 5.7.42-log

What behavior do you expect?

i expect that mysql's 'geometry' data type  can be normally  got and converted 

What behavior do you see?

i see connector's log  , the error message is "Failed to resolve column type for schema: STRUCT (io.debezium.data.geometry.Geometry)" in  log file.  

Do you see the same behaviour using the latest released Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)

i don't , i just used 3.0.0.Final version. but i see debezium-jdbc source code that 3.0 version,  , the MySqlDatabaseDialect.registerTypes() already registed the type 'GeometryType', i don't understand why tell me that "Failed to resolve column type for schema: STRUCT (io.debezium.data.geometry.Geometry)";

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)

this is my sink connector logs:
