引起：io.debezium.text.ParsingException：外部输入“ASC”期待

Question

我正在运行源 kafka 连接器，但不幸的是我遇到了以下错误：

在 debezium 日志中我得到以下错误：

我没有使用架构注册表和 avro。源数据库是 mysql。

我的其他源连接器工作正常。我无法识别错误。源 db 是第三方 db 可能有人更改了 db 中的任何内容，但据我了解，kafka 连接器也为此在 binlog 中进行了更改。所以可能这不是问题。

谁能告诉我这个问题和解决方案？

连接器配置：

curl -i -X POST -H "Accept:application/json" \
    -H  "Content-Type:application/json" http://localhost:38083/connectors/ \
    -d '{
    "name": "supplier-central",
    "config": {

        "value.converter": "org.apache.kafka.connect.json.JsonConverter"
    }
}'

当我在配置中使用不同的数据库名称和不同的表名称时出现此错误。检查您的配置database.whitelist 和table.whitelist 是否相互匹配或配置正确。
