Creating index based on Timestamp doesn't work

[jliunyu]

I'm trying to creating index monthly, this is the config I have, the connector version I'm using is 10.0.0 and the ES version is 6.8.0, we can't upgrade the ES version for now, so we have to config based on the version we have. the connector is able to read the config, but not the time stamp, index can't be created either. Can some one provide me some help on this?

this is my config

      topics: test
      transforms: Router
      transforms.Router.type: org.apache.kafka.connect.transforms.TimestampRouter
      transforms.Router.timestamp.format: yyyyMM
      log.message.timestamp.type: LogAppendTime
      transforms.Router.topic.format: test-${timestamp}

printed from the log

        transforms = [Router]
	transforms.Router.timestamp.format = yyyyMM
	transforms.Router.topic.format = test-
	transforms.Router.type = class org.apache.kafka.connect.transforms.TimestampRouter
