Infer type is empty in hono

In the auth.ts file , while following the hono better-auth docs. It states to infer the user and session type use auth.$infer. But in my case that is an empty object. I am binding that to Hono app by const app = new Hono<{Binding: AuthType}> which according to docs should set the type for users and session. this is the type that i get back when using auth.api.getSession() 
const session: {
    session: unknown;
    user: unknown;
} | null
const session: {
    session: unknown;
    user: unknown;
} | null
why is it unknown ?
Solution:
hello also check your config (like empty plugins array etc), had this kind of errors before too...

export type AuthType = {
    Variables: {
        user: typeof auth.$Infer.Session.user | null;
        session: typeof auth.$Infer.Session.session | null;
    };
};
export type AuthType = {
    Variables: {
        user: typeof auth.$Infer.Session.user | null;
        session: typeof auth.$Infer.Session.session | null;
    };
};

try this 
type SessionType = ReturnType<typeof auth.api.getSession>;
type SessionType = ReturnType<typeof auth.api.getSession>;
then use SessionType['user'] also I think you need to pass in the db for it to work

I do not get it .. why does this also have the session and use type as unknown ? 
type SessionType = Promise<{
    session: unknown;
    user: unknown;
} | null> & {
type SessionType = Promise<{
    session: unknown;
    user: unknown;
} | null> & {

even if i use Awaited<Promise>. the session is unknown 
type SessionType = {
    session: unknown;
    user: unknown;
} | null
type SessionType = {
    session: unknown;
    user: unknown;
} | null

another question in hono , is how should we bind the authtypes ? in the hono website the example given is like this 
const router = new Hono<{ Bindings: AuthType }>({
    strict: false,
})
const router = new Hono<{ Bindings: AuthType }>({
    strict: false,
})
but then i am getting error calling c.get("user")

you need to pass it as variables 
const router = new Hono<{ Variables: AuthType }>({
    strict: false,
})
const router = new Hono<{ Variables: AuthType }>({
    strict: false,
})
then in a middleware set the auth info with c.set
