Jenkins pipeline input message

Question

I have created jenkinsfile with input but I get a error. I do not know what is going on. Any idea?

Jenkinsfile

import groovy.json.JsonSlurper def approvalMap

pipeline {
    agent none

    stages {
        stage('Hello') {
            steps {
            
                script{
                    
                    def postmanGet = new URL('https://harbor.centos2.com/api/v2.0/projects/spring/repositories/crudrepository/artifacts?page=1&page_size=10&with_tag=true&with_label=false&with_scan_overview=false&with_signature=false&with_immutable_status=false')
                    def getConnection = postmanGet.openConnection()
                    getConnection.requestMethod = 'GET'
                    var= getConnection.getInputStream().getText()
                    JsonSlurper sl = new JsonSlurper()
                    def json = sl.parseText(var)
                    ArrayList array = new ArrayList(json.tags.name)
                    taglist = new ArrayList()
                    for  (String x : array){ taglist.add(x.first())}
                    
                    env.RELEASE_SCOPE = input message: 'User input required', ok: 'Release!',parameters: [choice(name: 'RELEASE_SCOPE', choices: taglist, description: 'What is the release scope?')]
                     
                }
            }
        }
    }
}

And error message. As we can see, Input message is visible. All data was imported from harbor ( list of tags) but this line cause below error. When I comment this line starts with "env.RELEASE_SCOPE" of course i have no error but also no input message.

Based on the types of classes involved in that stack trace, my guess is that the thread that Jenkins uses to execute the input step is trying to access the URL connection but can't.

As discussed here, the URL library doesn't have an explicit way to close the HTTP connection. And as discussed here, I believe the getText() method you're using already closes the input stream.

As a result, I would try using a different HTTP client, like Apache, that lets you explicitly close the HTTP connection before you get to your input step.

URL is correct beacause data to inputset is retrived. Error cause line env.RELEASE_SCOPE = input message: 'User input required', ok: 'Release!',parameters: [choice(name: 'RELEASE_SCOPE', choices: taglist, description: 'What is the release scope?')]
