spring cloud stream app starter File Source to Spring Batch Cloud Task

Question

I have a spring batch boot app which takes a flat file as input . I converted the app into cloud task and deployed in spring local data flow server. Next , I created a stream starting with File Source -> tasklaunchrequest-transform -> task-launcher-local which starts my batch cloud task app .

It looks like that the File does not come into the batch app . I do not see anything in the logs to indicate that.

I checked the docs at https://github.com/spring-cloud-stream-app-starters/tasklaunchrequest-transform/tree/master/spring-cloud-starter-stream-processor-tasklaunchrequest-transform

It says

Any input type. (payload and header are discarded)

My question is how do I pass the file as payload from File Source to the Batch app which seems to be a very basic feature.

any help is very much appreciated.

You'll need to write your own transformer that takes the data from the source and packages it up so your task can consume it.
