Using Effect Type with Option: Best Practices for Handling Errors with findIndex

declare const list: A[]

export const findIndex =
    (self: A): O.Option<number> =>
        RA.findFirstIndex(list, Equal.equals(self));

export const kills =
    (b: A) =>
    (a: A): Effect.Effect<never, never, boolean> =>
        Effect.gen(function* (_) {
            const indexA = yield* _(findIndex(a)); // <- Type 'Effect<never, NoSuchElementException, boolean>' is not assignable to type 'Effect<never, never, boolean>'
  Type 'NoSuchElementException' is not assignable to type 'never'
            const indexB = yield* _(findIndex(b));
            return (indexB - indexA + 5) % 5 === 1;
        });
