我正在尝试为MongoDB部署一个新的Debezium连接器和Transforms。配置如下：
{"name": "mongo_source_connector_autostate",
"config": {
"connector.class": "io.debezium.connector.mongodb.MongoDbConnector",
"tasks.max":1,
"initial.sync.max.threads":4,
"mongodb.hosts": "rs0/FE0VMC1980:27017",
"mongodb.name": "mongo",
"collection.whitelist": "DASMongoDB.*_AutoState",
"transforms": "unwrap",
"transforms.unwrap.type" : "io.debezium.connector.mongodb.transforms.UnwrapFromMongoDbEnvelope",
"transforms.sanitize.field.names" : true
}}
但是，连接器出现故障，并出现以下错误：

我已经在分布式模式下启动了连接器，配置如下：
...
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=http://localhost:8081
value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
...
注意：我有另一个没有任何转换的连接器。它运行得很好。
我想在这方面得到一些帮助。提前谢谢。
您的一个字段似乎违反了Avro命名规则。在你的情况下，它似乎是这样的：
全名的名称部分、记录字段名称和枚举符号必须：
- 从
[A-Za-z_]开始
但是10019_AutoState违反了规则，因为它以数值开头。您可以将其更改为类似AutoState10019的内容
您可以在此处查看带有所有记录字段命名约束的完整列表。
什么Debezium版本？如果1.1/1.2有问题，请提出Jira问题。架构名称需要清理，在我看来，在这种情况下，错误来自集合名称10019_AutoState，并且架构名称没有清理，因为它不能以数字开头。
