Hey @kazuhiro! :wave:

Here are three examples of running Selenium on Streamlit Community Cloud:

  1. @Franky1’s example:
  1. @snehankekre’s example:
  1. @randyzwitch’s example:

I hope these suggestions will help you in identifying and debugging the issue you’re facing.

If not, please let us know, and we’ll be happy to take another look! :blush:

Hi Charly! Thank you for your information, I could study about the error.
My app worked on streamlit cloud. Thank you so much.

fixed code

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options

options = Options() 
options.add_argument("--headless=new")
options.add_argument('--disable-gpu')

driver = webdriver.Chrome(options=options)

driver.get('https://www3.nohhi.co.jp/rktrace/trace.html')

search_bar = driver.find_element(By.NAME, "command5")
search_bar.send_keys(num)
search_bar.submit()
