Auto update custom field and system field during transition by using ScriptRunner in JIRA Cloud

Hi there

I'm trying to auto update a custom field and a system field during transition by using ScriptRunner in JIRA Cloud.

I'm want to use POST method. Take note that I've tried with actual value but keep getting error. I guess my body isn't correct. I'm new to Groovy. Kindly assist.

Please find below code.

// Specify here the issue key for the issue to transition
def issueKey = '<issue name>'

//check if issue is assigned
def result = get('/rest/api/2/issue/' + issueKey + '?fields=assignee')
.header('Content-Type', 'application/json')

if (result.body.fields.assignee.accountId != null)

// The ID of the workflow transition to execute.
// Note - The transition ID must represent a valid transition for the workflow that the issue uses.
def transitionID = '<transitionID>'

// The rest call to transition the issue
def transitionIssue = post("/rest/api/2/issue/${issueKey}/transitions")
.header("Content-Type", "application/json")
.body( [
fields: [
"customfield_10050": '5'
"summary": 'Task name from script'
transition: [id: transitionID]

// Check if the issue was transitioned correctly
if (transitionIssue.status == 204) {
return "The ${issueKey} issue was transitioned to the status with the id of ${transitionID}"
} else {
return "The escalation service failed to transition the ${issueKey}issue. ${transitionIssue.status}: ${transitionIssue.body}"

I've managed to solve this. I'm unable to use update custom fields in the transition as the fields were not available. I was unable to get the fields although I tried to change the screen types in workflow transition. 

So I managed to use PUT method to update fields.

See - adjusting a system field is just a case of using its name directly as you already are.
