Roblox API rejecting my question with 403? No further information

Question

I'm using roproxy instead of roblox to get around cord measures, requestbody is username,ctype ,password and useridand for the headers I'm just doing xcrs token:xcrs. It's just returning 403(). Is this an xcrs token thing? Couldn't find anything about it online. Ideally, it would print the incorect password error, or anything but 403() 0 heres the code im using

   const passwordcheck = {
   ctype: "Username",
    cvalue: "usernametomyaccount",
    password: "passwordtomyaccount",
    captchaToken: "CaptchaFromFuncaptcha",
    captchaId: "Captcha",
    captchaprovider: "PROVIDER_ARKOSE_LABS",
    userId: 889124,
  };

  const request = {
    method: "POST",

    headers: {
      "Content-type": "application/json",
      "X-csrf-token": "wiXzYTbS/xF3",
      Cookie: "",
      
    },
    body: JSON.stringify(passwordcheck),
  };

the url is roproxy v2 login

I've tried using different proxies, but nothing came off it. Filling out the requestbody with all the stuff in the Roblox auth documentation didn't work either.
