authClient.getSession wrong return type

when using authClient with

fetchOptions: {
    throw: true
  }

fetchOptions: {
    throw: true
  }

fetchOptions: {
    throw: true
  }

fetchOptions: {
    throw: true
  }

the return type is:

{
    user: { ... 11 more };
    session: { ... 9 more };
}

{
    user: { ... 11 more };
    session: { ... 9 more };
}

{
    user: { ... 11 more };
    session: { ... 9 more };
}

{
    user: { ... 11 more };
    session: { ... 9 more };
}

but it should be:

{
    user: { ... 11 more };
    session: { ... 9 more };
} | null

{
    user: { ... 11 more };
    session: { ... 9 more };
} | null

{
    user: { ... 11 more };
    session: { ... 9 more };
} | null

{
    user: { ... 11 more };
    session: { ... 9 more };
} | null

When there isn't an active session, null is returned on the /get-session endpoint. This was missing in types.
