SCDF stream (time) NOT picking composed-task-runner in local

Question

in SCDF (2.6.3) tried to create stream to launch composite task, but not picking, what am I missing?

Composed task created name as comp-task: AA && BB I can run manually run this composed task, it executed both AA and BB and exit normally.

When I tried to run through stream, it is not running at all even defined in cron. My task definition: stream create ctr-stream-1 --definition "time --cron='0 0/5 0 ? * *' --task.launch.request.task-name=composed-task-launcher --task.launch.request.args=--graph=comp-task,--increment-instance-enabled=true | task-launcher-dataflow"

You don't necessarily need to create a stream when you want to create/launch a composed task. This page walks you through how to create and launch a composed task as a task application.

If you want to schedule a composed task application, you also need to remember that scheduling a task application is not supported in local deployment.
