How to fix bad request in api Jira with comment

[Jerry]

Hi,

sorry if I'm in the wrong group.
I'm trying to create an issue in Jira through the webservice /jira/rest/api/2/issue.

I got it to work but when I try to add the comment if returns a 400 badrequest.
Can anybody tell me what the syntax should be for the comment?

This is my Json:

'{
"fields": {
"project":
{
"key": "NNL"
}
,"summary": "SUMMARY"
,"description": "DESCRIPTION"
,"issuetype":
{
"name": "Story"
}
,"components": [
{
"name": "imported"
}
]
,"customfield_10504": "TD1212"
,"comment": "Testing comment"
}
}'

Thank you 

Jerry

If you want to add a comment you need to use

POST /rest/api/2/issue/{issueIdOrKey}/comment

https://developer.atlassian.com/cloud/jira/platform/rest/#api-api-2-issue-issueIdOrKey-comment-post

Comment is not an issue field.
