Handling Nested Optional Fields in TypeScript Schema Transformations

const attempt = Schema.transform(
  Schema.Struct({
    foo: Schema.Struct({
      bar: Schema.optionalWith(Schema.String, { as: 'Option', nullable: true }),
    }),
  }),
  Schema.Option(Schema.String),
  {
    strict: true,
    encode: (value) => ({ foo: { bar: Option.getOrNull(value) } }),
    decode: (value) => value.foo.bar,
  },
)
