Using the JSON above, i get this error.
{    "errorMessages": [        "Invalid request. Could not parse request body."    ]}

How would i close the ticket? So basically mark it as Done / Completed.

What about using the following for comment in a body:

"comment": [
{
"add": {
"body": {
"type": "doc",
"version": 1,
"content": [
{
"type": "paragraph",
"content": [
{
"text": "Resolved via automation.",
"type": "text"
}]}]}}}]

It does not specifically show me how to close issues.
I would like to just get the json to get this right.
