session callback throws mongoose__WEBPACK_IMPORTED_MODULE_0___default(...).connect is not a function

[xmarya]

I'm using mongoose ^8.11.0 with Auth.js 5.0.0-beta.25
the problem is that is inside the signIn callback I can run this code and work without slightest problem:

const isExist = await getUser(user.email);
        console.log("isExist", !!isExist, isExist);

        // 2) if not exist then create a new user
        if (!isExist) await createNewUser(user);

but that is not the case in session callback where I'm calling the exact same controller:

async session({ session }) {

          const currentUser = await getUserOnEdge(session?.user.email);
          console.log("currentUser🔴", currentUser);

      // 1) adding the role and the id to the session info:
      // session.user.id = currentUser._id;
      // session.user.userType = currentUser.userType;
      return session;

    },

it throws mongoose__WEBPACK_IMPORTED_MODULE_0___default(...).connect is not a function
I knew recently -exactly yesterday- that is because mongoose doesn't run on the Edge runtime. ok I got this point but that doesn't make sense at the same time since everything goes well inside signIn callback!
