Let it crash.

The only time I can think of when I catch ecto errors like that is when I want an invalid UUID to be the same as a UUID that doesnt exist

```elixir
  @impl true
  def one(query, opts \\ []) do
    super(query, opts)
  rescue
    err in Ecto.Query.CastError ->
      if err.type == Ecto.UUID or match?({:in, Ecto.UUID}, err.type) do
        Logger.warning("Received invalid UUID #{err.value} in query #{inspect(query)}")
        nil
      else
        reraise err, __STACKTRACE__
      end
  end

```
