Pytest-bdd test getting type error 'NoneType' object is not subscriptable

[ArchanaICM]

I am trying to run pytest-bdd tests with conftest.py using fixtures at session level. After yeilding the setup data getting the below error
TypeError: 'NoneType' object is not subscriptable
can I get help how to get this fixed?
conftest.py

@pytest.fixture(scope="session", autouse=True, params=["chrome"])
def setup(request, read_user_input):
    web_driver = None

    try:
        browser_name=request.param
        # Initialize WebDriver based on browser_name
        with allure.step(f"Initialize WebDriver based on browser_name {browser_name}"):
            if browser_name == 'chrome':
                chrome_latest_version=chrome_version.get_chrome_version()
                web_driver  = webdriver.Chrome(service=ChromeService(ChromeDriverManager(chrome_latest_version).install()))
            elif browser_name == 'firefox':
                web_driver =webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()))
            elif browser_name == 'edge':
                web_driver = webdriver.Edge(service=EdgeService(EdgeChromiumDriverManager().install()))
            else:
                fail_with_log(f"Unsupported browser: {browser_name}")
            custom_log().info(f"Opened the {browser_name}  browser")

        yield web_driver,read_user_input,browser_name

    except Exception as error:
        custom_log().error(f'Unable to launch the browser {request.param} due to error: {error}')

    finally:
        #  Ensure the WebDriver is quit after the test runs if it was created

        if webdriver:
            with allure.step(f"Close the browser"):
                web_driver.quit()

features.py
Scenario: User successfully registers a demo account
Given the user is on the registration page
When the user enters valid details
And clicks the submit button
Then the account is created successfully

step_definitions.py - this is one sample steps

def test_create_demo_account(setup,get_run_date):
    try:
        custom_log().debug("test create demo starting")
        driver,user_input_dict,_=setup
        first_name_value = user_input_dict["first_name"]
        middle_name_value = user_input_dict["middle_name"]
        last_name_value = user_input_dict["last_name"]
        email_value = user_input_dict["email"]
        phone_number_value = user_input_dict["phone_number"]


        allure.attach(get_run_date, name="Test Run Date", attachment_type=allure.attachment_type.TEXT)

        # enter the first name
        with allure.step("input first name"):
            demo_registration_page(driver).input_first_name(first_name_value)

        # enter the phone number
        with allure.step("input phone number"):
            demo_registration_page(driver).input_phone(phone_number_value)

        custom_log().info("The user entered valid details")

    except Exception as error:
        custom_log().error(f"Unable to enter the valid details due to the error- {error}")
        raise error

@when("clicks the submit button")
def test_click_submit_button(setup):
    try:
        driver,_,browser_name=setup
        with allure.step("click on submit button"):

        custom_log().info("The demo account registration is submitted")

    except Exception as error:
        custom_log().error(f"Unable to proceed with the application due to the error- {error}")
        raise error

Why don't you ask in pytest-bdd? user_input_dict is probably None. There's no context to make any more guesses, though.

[ArchanaICM]

Thanks for getting back. Can confirm that user_input_dict is getting values. The error occurs exactly as this line "yield web_driver,read_user_input,browser_name
" during debug. Can you refer to the whole error message in the other reply?
PS- I am running the tests in virtual environment.

For starters, show the full traceback instead of only showing a tiny part of the error and making everyone guess.

Nothing of the error you show points to either pytest or pytest-bdd. This looks to be a PyCharm bug, actually: TypeError in pydevd_pep_669_tracing - TypeError: 'NoneType' object is not subscriptable using Python 3.13 : PY-76928
