Hello,

I am trying to run ANY example code at linux (Ubuntu server), headless server.

The main problem that i am facing, is that I can't comunicate with browser.

Traceback (most recent call last):
  File "test.py", line 12, in <module>
    print(scrape_heading_task())

The same code at windows pc works like a charm, maybe the botasaurus is not support linux servers?

Does this works:

from botasaurus.browser import browser, Driver

@browser(add_arguments=['--no-sandbox'])
def scrape_heading_task(driver: Driver, data):
    # Visit the Omkar Cloud website
    driver.get("https://www.omkar.cloud/")

    # Retrieve the heading element's text
    heading = driver.get_text("h1")

    # Save the data as a JSON file in output/scrape_heading_task.json
    return {
        "heading": heading
    }

# Initiate the web scraping task
scrape_heading_task()

Sollution found.

At ubuntu servers, we have to install virtual monitor First, you need to install Xvfb.

sudo apt-get update
sudo apt-get install xvfb

Start Xvfb on a specified display. For example, to start it on display :99, run:

Xvfb :99 -screen 0 1024x768x16 &
export DISPLAY=:99

Then the script works!

Also, if you run script like VM=true python main.py, it will then also work successfully
