Can't transition issue using REST API

[awqeiruyt478ryfd78h]

Hi all,

I'm currently attempting to set a ticket to More Information via the REST API. I've made a call to 

/rest/api/2/issue/{issueIdOrKey}/transitions?expand=transitions.fields

to get the available issues, and the one I want in particular seems to be this one:

{
 "expand": "transitions",
 "transitions": [
 {
 "id": "111",
 "name": "More Info",
 "to": {
 "self": "https://jira.WEBSITE.co.uk/rest/api/2/status/10005",
 "description": "",
 "iconUrl": "https://jira.WEBSITE.co.uk/images/icons/statuses/generic.png",
 "name": "More information",
 "id": "10005",
 "statusCategory": {
 "self": "https://jira.WEBSITE.co.uk/rest/api/2/statuscategory/4",
 "id": 4,
 "key": "indeterminate",
 "colorName": "yellow",
 "name": "In Progress"
 }
 },
 "fields": {
 "assignee": {
 "required": false,
 "schema": {
 "type": "user",
 "system": "assignee"
 },
 "name": "Assignee",
 "autoCompleteUrl": "https://jira.WEBSITE.co.uk/rest/api/latest/user/assignable/search?issueKey=ISSUE&username=",
 "operations": [
 "set"
 ]
 }
 }
 }
 ]
}

If I'm correct, I'm using the id of 111 to try and set my ticket to the status that I want it to be. My code looks as follows:

tickets.moreInfo = function(key) {
 var transitionUrl = 'https://jira.WEBSITE.co.uk/rest/api/2/issue/TICKET-REF/transitions';
 var transitionData = {
 "transition": {
 "id": "111"
 }
 };
 transitionData = JSON.stringify(transitionData);

 $.ajax({
 type: 'POST',
 url: transitionUrl, 
 data: transitionData,
 contentType: 'application/json',
 dataType: 'json'
 }); 
}

No matter what, I'm always returned with either a 400 or 500 error. I've tried both the IDs 111 and 10005. Any thoughts? Am I doing something obviously stupid? Thanks!

Log/inspect the actual response body of the request, if it's 400 or 500 there should be more detailed info regarding the error there.

I have same problem, but using curl. Any results from the sugestion?
