When i generate the groovy code with Snippet Generator to do input list
parameters like this :

input id: 'Server', message: 'Choose the server', ok: 'Proceed',
parameters: [[$class: 'ChoiceParameterDefinition', choices: ['Dev',
'Integ', 'Prod'], description: '', name: 'Server']]


i have this Error :

java.lang.ClassCastException:
hudson.model.ChoiceParameterDefinition.choices expects class
java.lang.String but received class java.util.ArrayList
