We are following below docuement to run child pipeline in scale parallel steps.  
[Advanced Workflows with Parallel steps · Codefresh | Docs](https://codefresh.io/docs/docs/codefresh-yaml/advanced-workflows/#scale-parallel-steps-one-dimension). Below is the sample code.

```auto
upgrade_pipeline version:
  type: freestyle
  stage: update
  arguments:
    PIPELINE_ID: 'blueprints/multi-repo-upgrader tool'
	  environment: 
	    - 'CF_REPO_OWNER="Github_Org"'
	    - 'CF_COMMIT_AUTHOR=$CF_COMMIT_AUTHOR'
	    - 'CF_COMMIT_MESSAGE=$CF_COMMIT_MESSAGE'
	    - 'SKIP_APPROVAL=true'
	    - 'DRYRUN_ONLY=${{DRYRUN_ONLY}}'
	    - 'BRANCH="test"'
	  scale:
	    upgrade-multi-repo-upgrader:
		  title: Upgrade pipeline version of Repo1
		  environment:
		    - 'CF_REPO_NAME="XXXXXXX"'
	    upgrade-hscmanishjainctr:
		  title: Upgrade pipeline version of Repo2
		  environment:
		    - 'CF_REPO_NAME="XXXXXXX"' 

```

Hello @manishjainctr

It is hard to answer this question without knowning how you have implemented the ` upgrade_pipeline version` plugin.

You need to ask the person that created it for the available options.

Alternatively please open an issue with us. Our support team will investigate. Be sure to include the Git repo that has the source code of this custom plugin.
