Code Snippet

Help us help you! Put down a short code snippet that illustrates your bug and
that we can run and debug locally.

        with sync_playwright() as p:
            self.browser = p.chromium.launch_persistent_context(user_data_dir=root_path+"/components/chromedata",headless=self.headless,ignore_default_args=["--inPrivate"])
            # self.context = self.browser.new_context(
            #     user_agent=USER_AGENT,accept_downloads=True,locale="zh-CN"
            # )
            self.page = self.browser.new_page()
            self.page.goto(url=pageUrl)
            for item in actionList:
                if "sleep" in item:
                    time.sleep(item["sleep"])
                self.page.wait_for_selector(item["selector"])
                pageElement = self.page.locator(item["selector"])
                if "click" == item["action"]:
                    pageElement.click()
                if "filechooser" == item["action"]:
                    pageElement.click()
                    # self.page.pause()
                    # 无法监控到爱奇艺的上传窗口。
                    self.page.on("filechooser", lambda file_chooser: file_chooser.set_files("/Users/fangluyu/tmp/Waves-70796.mp4"))

            self.page.close()
            self.browser.close()

When start Using page.on("filechooser") it seems does not work for me. It failed to set file to filechooser

from playwright.sync_api import sync_playwright, expect
import tempfile

with sync_playwright() as p:
    with tempfile.TemporaryDirectory() as tmp_dir:
      browser = p.chromium.launch_persistent_context(user_data_dir=tmp_dir, headless=False)
      page = browser.new_page()
      # https://playwright.dev/python/docs/api/class-filechooser
      page.goto("https://pw.rwoll.dev/file-uploads")
      with page.expect_file_chooser() as fc_info:
          page.locator("#file-uploader").click()
      file_chooser = fc_info.value
      file_chooser.set_files("foo.txt")
      expect(page.locator("body")).to_contain_text("Name: foo.txt, Size: 7")
      page.pause() # pausing test so user can manually look for demo purposes
      browser.close()

The above is working for me, assuming I have foo.txt in the directory next to my script. Can you create a small repro by modifying the above showing it break in the same way you are seeing?

NB: self.page.on("filechooser", lambda file_chooser: file_chooser.set_files("/Users/fangluyu/tmp/Waves-70796.mp4")) as the last line in your script looks like it would be flaky. You'll want to start listening for the event before you take the action that can trigger it.

My context:

Playwright Version: 1.25.2
Operating System: win10
Python version: 3.10
Browser: Chromium

In Safari and Firefox is working for me, but in Chromium it clicks to the input but it does not appear the filechooser and appears me this error:
playwright._impl._api_types.TimeoutError: Timeout 30000.0ms exceeded while waiting for event "filechooser"

Can you share a repro with us which we can run locally? Otherwise we can't act on it.
