Hi Streamsets community,

I am using StreamSets Data Collector 3.15.0 ( built by ubuntu on 2020-04-14T00:23Z )

I have an orchestration pipeline in which I use a parameter "batch". I have few doubts.

  1. The Pipeline that I am starting using start pipeline uses a parameter also named as "batch", So, do I need to pass this in start pipeline, or the parameter will be automatically overwritten by the orchestration pipeline parameter ? Ideally it should I think, but that is not the case.Please confirm.

  2. If parameter is not automatically overwritten, how to pass that parameter as runtime parameter in start pipeline. I have tried putting [ { "key": "batch", "value": "batch2" } ] in orchestration pipeline parameter and {"batch":"${batch}"} in start pipeline Runtime Parameters option. But when I run the orchestration pipeline I get

    An exception occurred while running the pipeline, java.lang.IllegalStateException: The template variable 'batch' has no value

What I am doing wrong, please guide.

A little confusing. Can you update your question and add screenshots of your pipelines and config?

I am not able to upload screenshots, don't have enough Karma. Can you tell me what part is confusing, I'll try to rephrase my query.

To sum it up simply, I am using an orchestration pipeline with parameter and I need to pass that parameter to a start pipeline runtime parameter, but I am not able to, I get "The template variable 'batch' has no value"

I figured out the issue, this was a bug in 3.15, it is fixed in 3.16, upgraded and issue got resolved.
