How to set value for single select custom field with REST API?

Philip Colmer

The "editmeta" response for a given issue includes this definition for one of the custom fields:

        "customfield_10166": {
            "required": false,
            "schema": {
                "type": "option",
                "custom": "com.atlassian.jira.plugin.system.customfieldtypes:select",
                "customId": 10166
            },
            "name": "Engineer Type",
            "key": "customfield_10166",
            "operations": [
                "set"
            ],
            "allowedValues": [
               {
                    "self": "https://linaro-development.atlassian.net/rest/api/3/customFieldOption/10331",
                    "value": "Assignee",
                    "id": "10331"
                },
                {
                    "self": "https://linaro-development.atlassian.net/rest/api/3/customFieldOption/10332",
                    "value": "Member",
                    "id": "10332"
                },
                {
                    "self": "https://linaro-development.atlassian.net/rest/api/3/customFieldOption/10333",
                    "value": "Affiliate",
                    "id": "10333"
                }
            ]
        }

If I try to set this field (e.g. with PUT /rest/api/latest/issue/<key>) on an issue with this body:

 

{
    "fields": {
        "customfield_10166": "Affiliate"
    }
}

it fails with this error: Specify a valid 'id' or 'name' for Engineer Type

I've tried the alternative format of specifying a value (using "update" instead of "fields") but I get the same error.

What am I doing wrong, please?

Use this:

{<br>   "fields": {<br>       "customfield_10166": {  "value": "Affiliate"}<br>&nbsp;  }<br>}
