How to create automation for a custom field with parent - child value

[Tomáš Chovanec]

"customfield_10055": {
                    "self": "https://xxxxx.atlassian.net/rest/api/2/customFieldOption/10177",
                    "value": "_Interní",
                    "id": "10177",
                    "child": {
                        "self": "https://xxxxx.atlassian.net/rest/api/2/customFieldOption/10192",
                        "value": "NG",
                        "id": "10192"
                     }                
}

Hi, I have trouble creating automation for custom field when the value is parent-child object.
But the child is optional.

{
  "fields": {
     "customfield_10055": "{{triggerIssue.fields.customfield_10055.asJsonObject("id")}}"
  }
}

I also tried many other possibilites.

And this is the error I get:

(Can not instantiate value of type [simple type, class com.atlassian.jira.issue.fields.rest.json.beans.CustomFieldOptionJsonBean] from JSON String; no single-String constructor/factory method (customfield_10055)) 

Thank you

Hi @Tomáš Chovanec ,

We don't support cascading select list as part of the simple forms yet (tracked here: AUT-327 ) so you'll need to use advanced fields. https://support.atlassian.com/jira-software-cloud/docs/advanced-field-editing-json/#field-syntax-examples

You'll want to use something like:

{
    "fields": {
        "Your Field": { "value": "{{triggerIssue.Your Field.value}}", "child": { "value" : "{{triggerIssue.Your Field.child.value}}"} }
    }
}

Cheers,
