Workfront API error "You do not have sufficient access to add this Issue"

Hi Team,

When I attempt to execute the issue creation API, I encounter the following error:

{
"error": {
"message": "You do not have sufficient access to add this Issue",
"title": "Access Denied",
"msgKey": "exception.attask",
"attributes": [""],
"code": 0
}
}

However, using the same user (session), I am able to execute other APIs such as fetching custom form details.

What could be the reason for this error? What level of access and permissions does the user need to create an ISSUE using the API?

Thanks
