Access-Control-Allow-Headers does not contain Comfy-User

[shinaji]

Hello.
I'm using ComfyUI with --enable-cors-header option.
When I call api with fetchApi(api.js), it embed Comfy-User into request header. However, due to Access-Control-Allow-Headers does not contain Comfy-User, I receive the following.
Is this expected behavior?

Request header field comfy-user is not allowed by Access-Control-Allow-Headers in preflight response.
