如何使用fp-ts将TaskOption转换为TaskEither？

import { pipe } from 'fp-ts/lib/function';
import { fromTask, Task } from 'fp-ts/lib/Task';
import { fromOption, TaskOption } from 'fp-ts/lib/TaskOption';
import { TaskEither, tryCatch } from 'fp-ts/lib/TaskEither';

function convertTaskOptionToTaskEither<A, B>(taskOption: TaskOption<A>, onError: (error: unknown) => B): TaskEither<B, A> {
  return pipe(
    taskOption,
    fromOption(() => onError('Value is None.')),
    fromTask,
    tryCatch,
  );
}

const taskEitherValue: TaskEither<string, number> = convertTaskOptionToTaskEither(taskOptionValue, () => 'Conversion Error');
