Hi,

Basically, what the rest call resturn is a JSON response.

First, try and do the call in Postman or another client where you can inspect the result.
The response might look something like this for the Approvers field:

 {
   "expand": "renderedFields,names,schema,operations,editmeta,changelog,versionedRepresentations","id": "10083",
   "self": "https://<your-site>.atlassian.net/rest/api/3/issue/10083",
   "key": "AUTBL-26",
   "fields": {
      "customfield_10003": [
            {
               "self": "https://<your-site>.atlassian.net/rest/api/3/user?accountId=557058%3Afbb39111-6fb5-4fa3-acca-2807f563c6df",
               "accountId": "<the account ID here>",
               "emailAddress": "someEmail@email.com",
               "avatarUrls": {
                  "48x48": "https://avatar-management--avatars.us-west-2.prod.public.atl-paas.net/557058:fbb39111-6fb5-4fa3-acca-2807f563c6df/55d30f27-0da5-45da-a670-91e420673421/48",
                  "24x24": "https://avatar-management--avatars.us-west-2.prod.public.atl-paas.net/557058:fbb39111-6fb5-4fa3-acca-2807f563c6df/55d30f27-0da5-45da-a670-91e420673421/24",
                  "16x16": "https://avatar-management--avatars.us-west-2.prod.public.atl-paas.net/557058:fbb39111-6fb5-4fa3-acca-2807f563c6df/55d30f27-0da5-45da-a670-91e420673421/16",
                  "32x32": "https://avatar-management--avatars.us-west-2.prod.public.atl-paas.net/557058:fbb39111-6fb5-4fa3-acca-2807f563c6df/55d30f27-0da5-45da-a670-91e420673421/32"
               },
               "displayName": "Jeroen Poismans",
               "active": true,
               "timeZone": "Europe/Brussels",
               "accountType": "atlassian"
            }
      ]
   }
}

 As you can see the Approvers field returns an array of objects. So let's try this:

def customfields1 = customFields[0].accountId

Hope this points you in the right direction!

yes i tried in this way too but in post-function script runner it shows warning like this

[Jeroen Poismans]

Ok, never mind the type error and lines ... Those are probanly there because of type checking.

I saw an error in my code, try something like this:

def customfields1 = customFields.fields.customfield_10507[0].accountId

No Jeroen there is still type checking errors exist  

btw why you are accessing 0th index of array object however the approver field account id is at first index i think.

[Jeroen Poismans]

Hi,

Never mind the type checking warnings, try executing the code (maybe in script console with an example issue) and see what real errors come out of it then ...

Now, if you inspect the JSON from my first reply you will see that the customfield contains an array. Inside that array the first Approver object is at index 0, not 1.

these are the error shows on execution

Hi,

Try this, this I have tested myself:

def result = get('/rest/api/2/issue/{issue.key}?fields=customfield_10507')
      .header('Content-Type', 'application/json')
      .asObject(Map)

if (result.status == 200){
   return result.body.fields?.customfield_10507[0].accountId
} else {
   return "Failed to find issue: Status: ${result.status} ${result.body}"
}

It's the part after the return statement that contains the data you want.

Jeroen
