Script Runner Post Function Script Condition

[Fawad_Haq]

jira cloud - I am using script runner cloud and using script post function feature to create a subtask after a transition based on check custom field value.  I am not sure what to add in the condition in the script context.  Still learn scripting so am a little week.  This is how far i got :

// Get all the fields from the issue as a Map
def fields = issue.fields as Map

// Get the Custom field to get the option value from
def customField = get("/rest/api/2/field")
.asObject(List)
.body
.find {
(it as Map).name == 'field name'

if it's a post function you can do this:

def MY_CUSTOM_FIELD_ID = 'customfield_10000'

def customFieldValue = issue.fields[MY_CUSTOM_FIELD_ID]

if(customFieldValue != 'Expected Value') {
    return
}

post("/rest/api/2/issue")
    .header("Content-Type", "application/json")
    .body([
        fields: [
            summary : "My Issue",
             description: "Hello World!",
             project : [
                 id: projectId
             ],
             issuetype : [
                 id: taskTypeId
             ]
         ]
    ]).asString()
