Trying to set people custom field via JIRA REST API

[Philip Colmer]

I want to set the list of people on a custom field using the JIRA REST API.

According to https://developer.atlassian.com/jiradev/jira-apis/jira-rest-apis/jira-rest-api-tutorials/jira-rest-api-example-create-issue, the syntax for setting a UserPicker is:

"customfield_10017": { "name":"brollins" } 

and according to https://developer.atlassian.com/jiradev/jira-apis/jira-rest-apis/jira-rest-api-tutorials/updating-an-issue-via-the-jira-rest-apis, the JSON sent needs to specify an update followed by the fields.

So, the JSON I'm sending is:

{
    'update': {
        'fields':
        {
            'customfield_10800': [{'name': 'fred.bloggs@example.com'}]
        }
    }
}

However, when I try to PUT this to the issue, I get the following message back:

Unexpected character (\'u\' (code 117)): expected a valid value (number, String, array, object, \'true\', \'false\' or \'null\')\\n at [Source: org.apache.catalina.connector.CoyoteInputStream@228b27b5; line: 1, column: 2]

Now, according to https://docs.atlassian.com/jira/REST/server/#api/2/issue-editIssue, fields should appear either in "fields" or "update" not in both. If I remove the "update" section, the error message changes to:

"Unrecognized token \'fields\': was expecting \'null\', \'true\', \'false\' or NaN\\n at [Source: org.apache.catalina.connector.CoyoteInputStream@228b27b5; line: 1, column: 8

I've tried double and single quotes.

I've run out of ideas :)

What have I got wrong in the data that I'm sending?

Assuming you are using a multi-user picker field, the following JSON should work:

{ "fields": {"customfield_10800": [{"name": "admin"}]} }

To set more than one user, you can do:

{ "fields": {"customfield_10800": [{"name": "admin"},{"name" : "philip.colmer"}]} }

Sorry, Sam, but if I try using that, I get this error:

Unrecognized token \'fields\': was expecting \'null\', \'true\', \'false\' or NaN\\n at [Source: org.apache.catalina.connector.CoyoteInputStream@21ab85b3; line: 1, column: 8

Hmm ... I've just retried this by using curl and it has worked so clearly I'm doing something wrong with the code.

Thanks for confirming the correct format.
