Answer 1

Promise.all takes an iterable, not multiple arguments. It tried to iterate your first argument, but that didn't have a [Symbol.iterator] method - "undefined is not a function". Pass an array:

await Promise.all([
    page.$eval('form', form => form.submit()),
    page.waitForNavigation(),
])
