Kafka将CDC连接到MSSQL“表必须至少具有一个主键列”

Question

我正在使用带有MSSQL连接器的Kafka Connect和启用CDC的数据库和表。使用REST API创建任务时，出现以下错误：

ERROR Exception thrown while querying for ChangeKey{databaseName=WebAppDb, schemaName=dbo, tableName=Companies} (io.confluent.connect.cdc.mssql.QueryService)

我不明白的是，该表具有主键：

那会是什么？

我发现这样做的原因是PK的名称。重命名为不带'。角色作品。应该是个错误。
