How to get result from previous task in a workflow ?

AurelienGravier — Fri, 12 Jul 2024 13:52:45 GMT

Hello,

In my workflow, I have a previous http request task with the following result :

I tried to use the value of "name" on the next task (http request) without success :

{
"eventType": "CUSTOM_INFO",
"title": "Loadtest start",
"timeout": 30,
"entitySelector": "type(APPLICATION),entityName.equals(XXXXXX)",
"properties": {
"Tool": "Octoperf",
"Load per minute": "100",
"Scenario name": "{{ result("launch_XXXXXXX_test2")["name"] }}"
}
}

I also tried with success :

"Scenario name": "{{ result("launch_XXXXXXX_test2")["json"]["name"] }}"

The error encountered is :

Could you help me how to get the right value from a task result ?

Thank you for your support.
Regards Aurélien

I solve it by using :

"Scenario name": "{{ result('launch_XXXX_test2').json.name }}"

But I don't find how to extract the name value with a custom JS task :

I encounter the exception below :

An error of type UNCAUGHT_EXCEPTION occurred in line 8 (col 39) " const name = await checkResult.json.name;": TypeError: Cannot read properties of undefined (reading 'name')
at default (file:///script.ts:8:39)
at eventLoopTick (ext:core/01_core.js:169:7)

Thank you.

Solved too !

// import of sdk modules import { execution } from '@dynatrace-sdk/automation-utils'; export default async function ({ execution_id }) { const exe = await execution(execution_id); const checkResult = await exe.result('launch_xxxxx_test'); const json = checkResult['json']; console.log('name : ', json.name); console.log('id : ', json.benchResultIds[0]); }

Hello @AK

I think you found it by yourself.

However, based on my previous comment, I would have done it like this. :

// optional import of sdk modules import { execution } from '@dynatrace-sdk/automation-utils'; export default async function({execution_id}) { const ex = await execution(execution_id); const data = await ex.result('check_rum_version'); const json = data['0']; console.log('appId : ', json.scope); }

Which "check_rum_version" is the name of the step corresponding to the http call.

Regards
