Next.js server actions auth

When I call from an action, the cookies are not sent - even if I insert “credentials”: “include”. Is there an example of how to call an external API via server actions?

have you added nextCookies()] plugin to your plugin lists. sever actions does not practically mutation browser info , you need the plugin to help you setting cookie with Set-Cookie header

I think I'm misunderstanding something about how it's meant to set cookies, because I'm not using asResponse and returning it because it's in useActionState so it can't return Response

can you please share the snippets ? if your server action does not return or redirect, the client may not update as expected.

you can do redirect since it causes client side navigation.

the session doesn't update though at least not for me (I've switched to using authClient instead, ditched useActionState with server actions)

may be something is affecting the responseHeader can you show me the how you are calling it on server actions

@KiNFiSH I've refactored it to use authClient now, but I'm still curious why the server action wasn't working so I've recreated it. Let me know what you think 🙂 
export const signInEmailSchema = z.object({
    email: z.string().email({ message: "Invalid email address" }),
    password: z.string(),
});

export const SignInForm: FC<ComponentPropsWithoutRef<"div">> = ({
    className,
    ...props
}) => {
    const signInEmail = async (prevState: unknown, formData: FormData) => {
        "use server";

        const submission = parseWithZod(formData, {
            schema: signInEmailSchema,
        });
        if (submission.status !== "success") return submission.reply();

        try {
            await auth.api.signInEmail({
                body: submission.value,
            });
        } catch (error) {
            if (error instanceof APIError) {
                return submission.reply({
                    formErrors: [error.message],
                });
            }
        }

        redirect("/");
    };
    const [state, formAction, pending] = useActionState(signInEmail, undefined);

    return (

Can use try using useTransition just to make sure it is not actually useActionState issue ?
