Having issue parsing github request

[lubronzhan]

Jenkins and plugins versions report

Plugin version: 2.2.5
Jenkins verison: 2.452.2
I was trying to use example

generic-webhook-trigger-plugin/src/test/resources/org/jenkinsci/plugins/gwt/bdd/github/github-pull-request.feature

Line 7 in 3e64913

| action | $.action | JSONPath | | |

here to parse the github post body using jsonPath
But github post body is wrapped in a payload element now. for example

{
    "payload": [
        {"action":"created"}
    ]
}

Then using $.action doesn't return anything for action.
Example jenkins config file I have

pipeline {
    agent {
        node {
        }
    }
  triggers {
    GenericTrigger(
     genericVariables: [
      [key: 'payload', value: '$.payload[0]'],
      [key: 'action', value: '$.action']
     ],

     causeString: 'Triggered on $action',

     token: 'token1',

     printContributedVariables: true,
     printPostContent: true,

     silentResponse: false,

     shouldNotFlatten: false,
    )
  }
  stages {
    stage('Some step') {
      steps {
        sh "echo $payload"
        sh "echo $action"
      }
    }
  }
}

Running the pipeline got below error

14:47:25  Also:   org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: f89c7f77-e85b-40d7-a209-583ddb326aa7

Even if I change from $.action to $.payload[0].action, still nothing returns. I can only get the output of $.payload[0]

Does anyone also run into this?

Works on my machine.

I created a pipeline like this:

 node {
 properties([
  pipelineTriggers([
   [$class: 'GenericTrigger',
     genericVariables: [
      [key: 'payload', value: '$.payload[0]'],
      [key: 'action', value: '$.action']
     ],

     causeString: 'Triggered on $action',

     token: 'token1',

     printContributedVariables: true,
     printPostContent: true,

     silentResponse: false,

     shouldNotFlatten: false,
   ]
  ])
 ])

 stage("build") {
  sh "echo $payload"
 }
}

I run that, manually, and I get your error. And that is totally ok, as long as the properties are applied and they are.

I trigger it with:

curl -v \
 -H "Content-Type: application/json" \
 -X POST \
 -d '{ "payload": [ {"action":"created"} ] }' \
 "http://localhost:8080/jenkins/generic-webhook-trigger/invoke?token=token1"

It triggers and logs:

 Received:

{ "payload": [ {"action":"created"} ] }


Contributing variables:

    payload = {"action":"created"}
    payload_action = created

Sorry forgot to put the jenkins version 2.452.2. Which jenkins version is yours? I guess it shouldn't be related to jenkins version?
I also tried your scripted jenkins file, I only saw payload got contributed, not payload_action

Contributing variables:
10:05:57  
10:05:57      payload = {"action":...

I directly use github to send the request, since curling our jenkins requires a crumb.

Right now the workaround I have is to parse that payload in the script to get information I need.
