What happened?

When use first Example Usage from https://codeigniter.com/user_guide/outgoing/api_responses.html
VS Code complains about Call to unknown method: CodeIgniter\HTTP\RequestInterface::getPost() at line:

$user  = $model->save($this->request->getPost());

When remove use ResponseTrait; then property $this->request changes
from: \CodeIgniter\HTTP\RequestInterface $request
to: \CodeIgniter\HTTP\CLIRequest|\CodeIgniter\HTTP\IncomingRequest

At runtime it works correctly only annoying VS Code highlights.

Steps to Reproduce

In test controller:

<?php

namespace App\Controllers;

use CodeIgniter\API\ResponseTrait;
use CodeIgniter\Controller;

class Users extends Controller
{
    use ResponseTrait;

    public function createUser()
    {
        $model = new UserModel();
        /**
        VS code popup on `$this->request`
        CodeIgniter\API\ResponseTrait::$request

        <?php
        public $request;
        @var \CodeIgniter\HTTP\RequestInterface $request
        */
        $user  = $model->save($this->request->getPost());

        // Respond with 201 status code
        return $this->respondCreated();
    }
}

Expected Output

Do no complain about unknow method getPost and is

Anything else?

No response

I had the same problem with phpstan version > 2.1.17 that marked methods in Controllers that extend ResourceController. Which uses ResponseTrait.
Furthermore it marked many more functions like: "Call to an undefined method CodeIgniter\HTTP\RequestInterface::getVar()" or getJSON() as errors.

Edit: Forgot to mention: Downgrading phpstan to version <= 2.1.17 fixed/hid the problem for me.

This is an IDE problem, as PHPStorm has no issues with this.
