playwright doesn't respond with systemctl service

Question

My server is running on Ubuntu 22.04.1 LTS and I have a python flask app which runs perfectly with an active virtual environment (source bin/activate) using wsgi [python 3.10]. While all my other routes are working fine, I can’t make playwright related routes run using systemctl service. For some reason it doesn’t react to my code and throws no Error. Any idea what am I doing wrong here?

#function that runs inside playwright route
    try:
        from playwright.sync_api import sync_playwright
        import sys
        print('n'.join(sys.path))

        with sync_playwright() as p:
            url = "https://www.wikipedia.org/"
            browser = p.chromium.launch(headless=True)
            Logger(f"opening {url} ...").info()
            context = browser.new_context()

            # Open new page
            page = context.new_page()
            page.goto(url)
            Logger(page.title(), 'is the title').log()

    except BaseException as error:
        print('An exception occurred: {}'.format(error))

here is the console log of the function above:

For future visitors, the playwright needs access to your /usr/bin and my initial approach of adding different bin directories was wrong. I should have used the following code to extend the PATH:
Environment="PATH=$PATH:/usr/bin"

my server is working fine now.
