[FIXED] How to get the payload information from jfrog webhook trigger on jenkins

Issue

I'm setting up a jenkins job which will be triggered whenever a artifact is deployed in jfrog. I have followed the steps present in the below documentation and i was able to trigger the job.But unfortunately, i'm not able to get the variables values.I'm not sure how to see the payload which we are receiving on the jenkins side to pull the required variables.Guide me

https://www.eficode.com/blog/triggering-jenkins-pipelines-on-artifactory-events

My pipeline:

pipeline {
    agent any
    
    triggers {
        GenericTrigger(
            genericVariables: [
                [key: 'ARTIFACT_NAME', value: '$.artifactory.webhook.data.name'],
                [event: 'EVENT_NAME', value: '$.artifactory.webhook.event']
            ],
            causeString: 'Triggered on $ARTIFACT_NAME'
        )
    }

    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
            }
        }
    }
}

Solution

I have made it. We have to enable print post contents in configure jenkins job under generic webhook trigger option. Once done it started to display json payload in console log. After that we can add variables using jsonpath filter from payload
