Issue is missing required information or the lack of permission?

[hafsa.kh91]

Error message: Cant move {issue}, you might not have permission, or the issue is missing required information. If you keep having this issue, contact your jira administrator. Error 400.

Here is the URL i am using:

https://{company}.atlassian.net/rest/api/2/issue/{issuekey}/transitions

and i want to change the status and comment on the issue:

{

    "update": {

        "comment": [

            {

                "add": {

                    "body": "Bug has been fixed."

                }

            }]

},

"transition": {

"id": "5"

}

}

I have written it exactly like this, but it shows me the above error. I have gotten a personal token that works when I try with Get issue in Jira, but not with Post. Is there some missing information here that I am missing? I am using windev so the rest of the full code, if relevant is below:

statusChange is string = [

{

    "update": {

        "comment": [

            {

                "add": {

                    "body": "Bug has been fixed."

                }

            }]

},

"transition": {

"id": "5"

}

}

]

QrySearch is restRequest
QryResponse is restResponse

QrySearch.URL = "https://{company}.atlassian.net/rest/api/2/issue/{issuekey}/transitions"
QrySearch.Method = httpPost
QrySearch.ContentType = "application/json"
QrySearch.Content = statusChange
QrySearch.User = {email address}
QrySearch.Password = {personal token key}

QryResponse = RESTSend(QrySearch)

IF QryResponse.StatusCode = "204" THEN

Info("Updated")

ELSE

Info("Fail", QryResponse.Content, QryResponse.StatusCode)

END

Please tell me what I am doing wrong?
