Getting a 404 on useSession and unable to use Svelte Store

// Current calls
const useSessionData = authClient.useSession(); // 404
const getSessionData = authClient.getSession(); // 200

// Example usage
<script lang="ts">
  import {authClient} from "$src/auth.client.ts";

  const session = authClient.useSession();
</script>

<main>
  <p>
    {$session.data?.user.email}
  </p>
</main>

`session` is not a store with a `subscribe` method
