Check out running a Workflow from a Workflow (sub-Workflows): Run workflow action for Workflows — Dynatrace Docs

Hello @heramb_sawant ,

First of all, add a task to generate your applications list.

Afterwards, create a child task and use the Loop Task option by adding the List related to the previous task and use a item variable name :

And finally you can use {{ _.item }} or in case of the Run JavaScript action, you can use loopItem function to access the item in each iteration :

Hi
I built 2 workflows

workflow 1 - having "run workflow" task . In loop task, there is item variable name "item" and its value is json object i.e.
[{

"cluster" : "Cluster1",
"namespace" : "namespace1"

},
{
"cluster" : "Cluster2",
"namespace" : "namespace2"

}

]

This workflow calling another workflow i.e workflow2.

Here in workflow2 , I am trying to print item values of workflow 1 but getting error in javascript code.

console.log(loopItemValue.value);

error : can not read properties of null(reading 'value)

Please correct me

Hello @heramb_sawant

You should use something like that :

// import of sdk modules import { execution } from '@dynatrace-sdk/automation-utils'; export default async function ({ loopItemValue }) { // load the execution object using the current loopItemValue const exe = await execution(loopItemValue); const checkResult = await exe.result('workflow1'); const json = checkResult['json']; // APPELER L'ATTRIBUT NAME console.log('Cluster : ', json.cluster); console.log('Namespace : ', json.namespace); }

@heramb_sawant

I’m not sure I fully understand what you mean.

You’re talking about a “workflow 1” and a “workflow 2,” whereas I’m referring to "tasks" within the same workflow.

In my case, you run check-result on the previous task name, which returns the JSON.

I am trying to call workflow 2 from workflow 1.

Workflow 1 has task that calls workflow 2. This task also has loopitem i.e. "item" having json object as value.
Then trying to access this loopitem values in workflow 2 but getting error.

Ok, so to assist you further,

Export your workflow as a template (make sure it doesn’t contain any personal data),

Or Take a screenshot of Workflow 1 and another screenshot of the results of the task that calls Workflow 2.

Ok, I understand your need better.

I have never experimented with this, but in my opinion you need to add {{ _.item }} in your input:

And you must use the input() expression in the sub-workflow :

{{ input('language') }} {{ input('topic') }
