NextAuth Cookie not being set in production

I have a React + Nextjs application which uses NextAuth. I'm trying to set a refresh token in a cookie which works fine on localhost but doesn't work when deployed on to production (HTTPS). The function setting the cookie is shown below. Is there something that I've missed?

From [...nextauth].ts:

const setRefreshTokenCookie = (
  cookies: Cookies,
  refresh_token: string
): Cookies => {
  const date = new Date();
  const time = date.getTime();
  const expireTime = time + 24 * 60 * 60 * 1000 * 90; // 90 days
  date.setTime(expireTime);

  const currentCookies = cookies.set(
    `${useSecureCookies ? "__Host-" : ""}test.refresh-token`,
    refresh_token,
    {
      sameSite: "strict",
      overwrite: true,
      expires: date,
      httpOnly: useSecureCookies,
    }
  );
  return currentCookies ;
};

Notes:

NextAuth's useSecureCookie

localhost cookies:

• test.csrf-token
• test.refresh-token
• test.callback-url
• test.session-token

production cookies:

• __Host-test.csrf-token
• __Secure-test.callback-url
• __Secure-test.session-token
