I am trying to set cookies after succesfull credential login using next auth

  setCookie({ res }, "name", "value", {
          maxAge: 2 * 24 * 60 * 60,
          path: "/",
          httpOnly: true,
        });

        if (user.user.isAdmin) {
          console.log("set cookie");
          setCookie({ res }, "userIsAdmin", "1", {
            maxAge: 60 * 60,
            httpOnly: true,
            path: "/",
          });
        }

The first setCookie function is for testing purposes to see if the if block has an effect on it. None of these work. When I check in the Application.Cookies tab i see neither a "userIsAdmin" cookie or "name" cookie.
setCookie is imported from the nookies npm package.
This is the full authorize function:

    async authorize(credentials): Promise<UserCustom | null> {
      if (!credentials?.username || !credentials?.password) return null;
      const { username, password } = credentials;
      try {
        const res = await fetch(
          `${process.env.FOODBASKET_AUTH_API_URL}/pos-user/login`,
          {
            method: "POST",
            body: JSON.stringify({ username, password }),
            headers: {
              "Content-Type": "application/json",
            },
          }
        );

        if (!res.ok) {
          const error = await res.json();
          throw new Error(error.message);
        }

        const user = await res.json();

        setCookie({ res }, "name", "value", {
          maxAge: 2 * 24 * 60 * 60,
          path: "/",
          httpOnly: true,
        });

        if (user.user.isAdmin) {
          console.log("set cookie");
          setCookie({ res }, "userIsAdmin", "1", {
            maxAge: 60 * 60,
            httpOnly: true,
            path: "/",
          });
        }

        return user;
      } catch (error: any) {
        console.log({ error });
        throw new Error(error.message);
      }
    },
