A problen encountered when connecting to tableau using the index kafka service function of druid

I am trying to connect druid to tableau with the kafka index service feature,and I have encountered a problem after the connection is successful.

There is no database available.

Has anyone encountered this problem?

When I use the kafak index service function, can druid be connected to tableau?

Someone has had the same problem, but it seems to have not been resolved.

Does it work with any other JDBC client? Or how about the “dsql” command line program that comes with Druid?
