I'm trying to implement API REST.

By following the documentation at : https://documenter.getpostman.com/view/29959/mantis-bug-tracker-rest-api/7Lt6zkP#16677869-82ac-50a0-e69f-c33986fbcf5f

I have an issue with the POST request for the creation of a project.
I use this payload :

{
   "name": "test1231231",
   "status": {
      "name": "development"
    },
    "description": "",
    "file_path": "/tmp/",
    "view_state": {
      "name": "private"
    },
    "enabled": true
}

Each time i try with a different name, i get an ERROR 500.
If i try to do the same call (with the same name), i get an ERROR 400 : {"message":"Project name is not unique","code":701,"localized":"A project with that name already exists. Please go back and enter a different name."}

So with the first call, the project is created successfully, however i dont get a return code 201 with the project_id.
by checking apache2 error.log, i have this line :

PHP Fatal error: 200 in /var/www/mantisbt/core/gpc_api.php on line 68

I use php 8.2.20
