Почему мой возврат на страницу page.on не работает должным образом

Question

В моем коде кукловода / javascript ниже я получаю результат, отличный от ожидаемого. Я не уверен, почему?

Я ожидаю, что значение "my json" будет возвращено внутри "price_ json" , однако это возвращает все элементы из браузера, как вы можете видеть из фактического результата.

Я не уверен, что мне не хватает базовых c javascript знаний, однако я сделал то же самое с оцените страницу, и это, кажется, работает нормально ....

Код -

const price_json = await page.on('response', async (response, i) => {
        const myjson = await response.json();
        console.log("inside of the page.on")
        console.log(myjson)
        console.log("inside (end) of the page.on")
        return myjson
  }, i);

  console.log(price_json)

Ожидаемый результат - (мой json выглядит так)

{ unit_price: '$39.65',
  carton_price: '$237.92',
  stock_code: '66121' }

Фактический результат - (цена_ json после возврата ...)
