Declarative pipeline: "Data generation failure: null" in input step

[Sascha Schwarz]

Hi!
The following Code just produces an empty dropdown list and an error message: Data generation failure: null

pipeline {
    options {
        buildDiscarder(logRotator(numToKeepStr: '3', artifactNumToKeepStr: '3'))
    }
    agent none
    stages {
        stage('input') {
            steps {
                input(
                    id: 'userInput', message: 'Text goes here', parameters: [
                        [ $class: 'DropdownAutocompleteParameterDefinition', name: 'MyName', dataprovider: [
                            [$class: 'InlineJsonDataProvider', autoCompleteData: '[{"id":"1"},{"id":"2"}]'
                ]]]])
           }
        }
    }
}

How do I use the InlineJsonDataProvider correctly? Jenkins V 2.60.2 Autocomplete Parameter Plugin V 1.0 Thanks Sascha

Hey,

It seems you are missing the displayVersion and valueExpression attributes.

The below snippet works, 

...

input id: 'userInput',  message: 'Text goes here', parameters:

    [[

        $class: 'DropdownAutocompleteParameterDefinition',

        name: 'MyName',

        dataProvider: 

        [

            $class: 'InlineJsonDataProvider', 

            autoCompleteData: '[{"id":"1"},{"id":"2"}]'

        ],

        displayExpression: 'id',

        valueExpression: 'id'

    ]]

...

Cheers

Thank you! :)

It seems that the displayVersion Parameter must not be null. :/

Thanks again
