How to fetch based on session? Getting 'session possibly null' with useQuery...

Let's say I am getting the

session

session

from the

useSession

useSession

hook and with ReactQuery I am setting the

enabled

enabled

status if the user is authenticated like so:

const { data: userProjects } = api.project.getByUserId.useQuery(
  {
    userId: session.user.id,
  },
  {
    enabled: status === "authenticated",
  }
);

const { data: userProjects } = api.project.getByUserId.useQuery(
  {
    userId: session.user.id,
  },
  {
    enabled: status === "authenticated",
  }
);

If I keep my code like this I get the error mentioned in the title, so how can I tell TypeScript that's safe doing so because we will run the query only if the user is authenticated?

Instead, if I change it to

session?.user.id

session?.user.id

I get the "Overload matches error" ending with

Type 'undefined' is not assignable to type 'string'.

Type 'undefined' is not assignable to type 'string'.

Does anyone have an advice?
