    Description

      Debezium version: 1.5.0.Final

      Connector failed on init on io.debezium.DebeziumException: io.debezium.text.ParsingException: DDL statement couldn't be parsed

      This is the full created table statement as it exists in the DB (I renamed some fields for security purposes)

       

      CREATE TABLE `_my_fake_table` (
       `something_fake_with_id` varbinary(16) NOT NULL,
       `another_fake_thing_with_id` varchar(36) COLLATE utf8mb4_bin GENERATED ALWAYS AS (json_value(`another_fake_thing`, _utf8mb4'$._somefield' returning char(36) character set latin1)) STORED NOT NULL,
       `another_fake_thing` json NOT NULL,
       PRIMARY KEY (`something_fake_with_id`,`another_fake_thing_with_id`)
      ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin ROW_FORMAT=COMPRESSED
      

      This is the error we get from the connector
