[Bug]: Download.failure() raises TypeError: expected string or bytes-like object, got 'NoneType'

[heisenborg-actual]

Version

1.43.0

Steps to reproduce

from playwright.sync_api import sync_playwright

with sync_playwright() as playwright:
    browser = playwright.chromium.launch()
    page = browser.new_page()
    with page.expect_download() as download:
        try:
            page.goto('https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf')
        except:
            pass
        print(download.value.path())
        print(download.value.suggested_filename)
        print(download.value.failure())

Expected behavior

I expect the call to download.failure() to return None because the download was successful.

Actual behavior
