[BUG]: Selenium 4.XX returns a dictionary for a WebElement

[mario-s]

Hi,

im trying to run a setup with with selenium xpra and Selenium 4.0.0/4.1.0. The browser starts and I'm able to navigate to a webpage and find an element. However the elemnt is not of type selenium.webdriver.remote.webelement.WebElementit is of type dict. So that means I can not interact with it via a click() action. Is the docker infrastructure not compatible with Selenium 4.x.x?

I'm using Python 3.8.5 with this is docker-compose file:

version: "3.3"

services:

  db:
    image: postgres:11-alpine
    ports:
      - "5432:5432"
    volumes:
      - ./db/sql/init.sql:/docker-entrypoint-initdb.d/init.sql
    restart: always

      - "8086:10000"

    networks:
      - healenium

volumes:

When I execute this python script, I get a dictionary, not the WebElement, as expected.

from selenium import webdriver
from selenium.commons.webdriver import By

firefox_options = webdriver.FirefoxOptions()
driver = webdriver.Remote(command_executor='http://localhost:8085', options=firefox_options)
driver.get("https://mdn.github.io/web-components-examples/life-cycle-callbacks/")
btn = driver.find_element(By.XPATH, '//button[contains(@class, "add")]')
type(btn)

Update to this topic:

When I remove the Xpra container and launch a standalone Selenium 4.1.2 server on my machine, it neither works with Selenium 4 and the Proxy. Here are my setups and the outcomes.

• standalone Selenium 4.1.2 server + Selenium 3.141.0 remote driver: success
• standalone Selenium 4.1.2 server + Healenium proxy (0.2.1) + Healenium Backend (3.2.0) + Selenium 3.141.0 remote driver: sucess
• standalone Selenium 4.1.2 server + Selenium 4.0.0 remote driver: success
• standalone Selenium 4.1.2 server + Healenium proxy (0.2.1) + Healenium Backend (3.2.0) + Selenium 4.0.0 remote driver: fail

The response from the proxy during a lookup for an element is different to the one from the server itself. Proxy:

{
    "value": {
        "ELEMENT": "4264a7dc-e356-49f4-b7d4-ae40986ad9a8"
    }
}

Selenium Standalone Server:

{
    "value": {
        "element-6066-11e4-a52e-4f735466cecf": "4264a7dc-e356-49f4-b7d4-ae40986ad9a8"
    }
}
