Steps to reproduce the issue

Use Postman to create an Article
/content/articles

With no Admin Plugin installed/enabled this Works Fine. You can use the boxplus Plugin or others to reproduce.

With Demo body:
{
"alias": "my-article-3",
"articletext": "My text",
"catid": 126,
"language": "*",
"metadesc": "",
"metakey": "",
"title": "Here's an article"
