We need the proper JSON format to import the custom field 'Organizations' (a.k.a. customfield_11900 and/or a.k.a. cf[11900] )
Also, is cf[11900] considered a true 'custom field' and needs to be populated in "customFieldValues"segment of the JSON file. And, do we set the field type as "fieldType": "com.atlassian.jira.plugin.system.customfieldtypes:multiuserpicker"?
Can someone answer this, please?
