1. Setting on spring boot:

private ResponseCookie makeResponseCookie(String refreshToken,Long refreshTokenValidationTime){
        return  ResponseCookie.from("refreshToken",refreshToken)
                .httpOnly(false)//  for access on javascript 
                .secure(true)// only on https 
                .path("/")
                .maxAge(refreshTokenValidationTime)
                .sameSite("None") // for access on different domain 
                .build();
    }

2. On React code :

  const reissueToken = async () => {
    const url = apiAddress + "/api/v1/auth/reissue";
    const refreshToken = Cookie.get("refreshToken");

    console.log("Refresh Token:", refreshToken);

    const response = await fetch(url, {
      method: "POST",
      headers: {
        "accessToken": token,
        "refreshToken": refreshToken
      },
      credentials: 'include',
    });

If i test on localhost, We can find Cookie on Chrome application tab!
enter image description here

But i can’t access cookie by above code! with refresh token is undefined

enter image description here

and it works on deployed frontend webpage!

I think it’s a matter of domain( frontend , backend on same ec2 using reverse proxing & same domain)

But Why????(localhost & spring boot server also applied https)

I set sameSite None on Spring boot and i expected it works!

1. What is my problem
2. How can i Test cookie on localhost(frontend)

i tried almost eveything lol
