Amazon s3 合流Kafka S3源连接器不工作-组数必须为正

Confluent Kafka Connect S3源连接器不工作，出现以下错误并出现故障，以下是配置。有人能帮我解决这个问题吗

配置

"name": 'test_s3_source',

"config": {
    "connector.class": "io.confluent.connect.s3.source.S3SourceConnector",
    "s3.region": "us-east-1",
    "s3.bucket.name": "s3-bucket",
    "confluent.license" : "" ,
    "confluent.topic.bootstrap.servers" :  "bootstrap-servers",

这里有更新吗？因为我也遇到了同样的例外。看起来它可能是在谈论正则表达式组。您的转换会将每个文件转换为名称为“test.s3.storage”。您可能需要“test.storage.source\u0”之类的内容。这里有更新吗？因为我也遇到了同样的例外。看起来它可能是在谈论正则表达式组。您的转换会将每个文件转换为名称为“test.s3.storage”。您可能需要类似“test.storage.source\u0”的内容
