Scriptrunner listener log returns "data was not an object"

[Joshua Sneed]

I have assembled a script listener to copy the contents of a system field (Assignee) to a custom Field (Assigned To) when an event (Issue Updated) is triggered. I have limited it to one project (ATS) and would like it to only run against the issue that triggered the event.

I have assembled the script from two available via Adaptavists website, the Copy Custom Field Values and the Calculate Custom Field On Issue Update. Using the Copy Custom Field Values wants to run agains all issues that meet the JQL query on the second line. The Calculate Custom Field On Issue Update only runs against the issue that triggered it and works wonderfully elsewhere on our instance.

The script 'completes successfully,' but leaves this error:

2018-01-30 22:16:52.816 INFO - Serializing object into 'interface java.util.Map'

 Here is my script:

package com.adaptavist.sr.cloud.samples.events

def sourceFieldName = 'Assignee'
def targetFieldName = 'customfield_14047' //'Assigned To'
def result = get("/rest/api/2/issue/${issue.key}" )
    .header('Content-Type', 'application/json')
    .asObject(Map)

// We retrieve a list of all fields in this JIRA instance
def fields = get("/rest/api/2/field")
    .asObject(List)
    assert fields.status == 200

List<Map> allFields = fields.body

// Now we lookup the field IDs
Map sourceField = allFields.find { it.name == sourceFieldName }
Map targetField = allFields.find { it.name == targetFieldName }

put("/rest/api/2/issue/${issue.key}")
    .header("Content-Type", "application/json")
    .body([
    fields:[
    (targetFieldName): sourceField.key
    ]
])
   .asString()

Hey

try this:

package com.adaptavist.sr.cloud.samples.events

def result = get("/rest/api/2/issue/${issue.key}")
 .header('Content-Type', 'application/json')
 .asObject(Map)

def s = result.fields.assignee
if(s != null){

put("/rest/api/2/issue/${issue.key}")
 .header("Content-Type", "application/json")
 .body([
 fields:[
 customfield_11925 : s
 ]
 
 
])
 .asString()

}

This looks weird to me:

(targetFieldName): sourceField.key

You are setting the "key" of the assignee field (not its value) to the  #14047 custom field?

I think this is the culprit. Check what is the body you are PUTting to the REST end-point.
