Update:

Using the following im unable to null out all groups assigned.

if (replica.labels.findAll { it.label.startsWith("reassign") } && !replica.labels.findAll { it.label.startsWith("customer_") }) {

    issue.customFields."Group Assigned".value = null

}

Any Idea on how to just null the field you dont want?

Example of what im attempting to do.  For our Jira Cloud Instance, we want to reassign the ticket back to Customer Service in Zendesk.  So we add the group assigned to Customer Service along with the group that was assigned originally.

When they CS team reassign back to Jira, we want the Customer Service Group to go away.

Hi David,

I would consider to achieve this by doing a custom trigger to something like:

With Exalate you can achieve it, but it will require advanced knowledge on doing API calls. Let me know if this works for you.

Kind regards,

Hey Ariel,

No this is for Jira, so you cant do a trigger.  What i have working right now, is to null out the group assigned.  My end goal is just remove the Customer Service Group and leave the original group assigned.

if (replica.labels.findAll { it.label.startsWith("reassign") } && !replica.labels.findAll { it.label.startsWith("customer_") }) {

    issue.customFields."Group Assigned".value = null

    issue.customFields."Group Assigned".value ?: ["name":"Service Desk Team"]

}

We tried to add the array value back manually to see if it worked, and it does not.

Here is the local replica.  So we are trying to remove from the array the value with "name":"Customer Service"

"customFields": {
      "Group Assigned": {
        "id": 10056,
        "name": "Group Assigned",
        "uid": "10056",
        "type": "UNHANDLED",
        "value": [
          {
            "name": "Customer Service",
            "self": "https://atlassian.net/rest/api/2/group?groupname=Customer+Service"
          },
          {
            "name": "Service Desk Team",
            "self": "https://atlassian.net/rest/api/2/group?groupname=Service+Desk+Team"
          }
        ]
      }

Sorry, I thought you were referring to Zendesk. Is this custom field a group picker? The payload says it is unhandled, is this custom field inserted by an external plugin?

Kind regards,

Ariel

Its a group picker, which assigns the ticket to a Jira Group to address.  Emails notifications to the group ... etc... etc...  Custom Field.  I had to create.

Hi David, 

Have you checked on this? :

We tried that:

    def restApiGroup = ["name":"Service Desk Team"]

    issue.customFields."Group Assigned".value = restApiGroup

Could not update issue `58,775`: Field customfield_10056: Operation value must be an array of group objects. Check the documentation for more details.

Hi David,

If you describe a bit more how you tried? What outgoing, Incoming scripts were used? Not sure if I understood what you are trying out here:

    def restApiGroup = ["name":"Service Desk Team"]
    issue.customFields."Group Assigned".value = restApiGroup

Kind regards,

Ariel

As you can see, the input coming in is a standard array:

"customFields": {
      "Group Assigned": {
        "id": 10056,
        "name": "Group Assigned",
        "uid": "10056",
        "type": "UNHANDLED",
        "value": [
          {
            "name": "Customer Service",
            "self": "https://atlassian.net/rest/api/2/group?groupname=Customer+Service"
          },
          {
            "name": "Service Desk Team",
            "self": "https://atlassian.net/rest/api/2/group?groupname=Service+Desk+Team"
          }
        ]
      }

So what we are trying to do is remove the Value name: "Customer Service" or  set the value to the second in the array.
The issue.customFields."Group Assigned".value should be assigned to 

"value": [ {"name": "Service Desk Team", "self": "https://atlassian.net/rest/api/2/group?groupname=Service+Desk+Team" } ]
