Hi NodeBB team,

I have NodeBB running locally on my machine:

NodeBB version: v3.12.7

Environment: Local development

Frontend: React (Vite) running on http://localhost:5173

Backend (NodeBB) running on http://localhost:4567

I’m trying to create a user via the API:

async function registerUser() {
  try {
    const res = await fetch(`${import.meta.env.VITE_API_URL}v3/users`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "Authorization": `Bearer ${import.meta.env.VITE_TOKEN}`
      },
      body: JSON.stringify(formData),
    });

    if (!res.ok) {
      throw new Error(`HTTP error! Status: ${res.status}`);
    }

    const data = await res.json();
    console.log("User registered successfully:", data);
  } catch (error) {
    console.error("Error registering user:", error);
  }
}

Question:
How can I correctly configure NodeBB in development so that it allows the Authorization header in API requests?
Even after setting Access-Control-Allow-Headers in the ACP, the browser still fails at the preflight request.
Do I need a plugin or middleware to handle CORS for API v3 routes?
