[Python] TypeError: Controller.action() missing 1 required positional argument: 'self' on...

I have an AI Agent for which i have written a controller using Python 3.13 and Playwright.

@Controller.action(description='Get attribute and url of the page')
async def get_attr_url(self, browser: BrowserSession):
page = await browser.get_current_page()
current_url = page.url
some_attribute = await page.get_by_text('swwg labs').get_attribute('class')
print(current_url)
return ActionResult(extracted_content = f'The current URL is {current_url} and the attribute is {some_attribute}')


i call them as follows :

controller = await Controller(output_model=CheckoutResults) //CheckoutResults-its another class.


i have tried two different ways with same results . please help.

1. class Controller:
@Controller.action(description='Get attribute and url of the page')
async def get_attr_url(self, browser: BrowserSession):
page = await browser.get_current_page()
current_url = page.url
some_attribute = await page.get_by_text('swwg labs').get_attribute('class')
print(current_url)
return ActionResult(extracted_content = f'The current URL is {current_url} and the attribute is {some_attribute}')


2. class Controller:
@staticmethod
@Controller.action(description='Get attribute and url of the page')
async def get_attr_url(self, browser: BrowserSession):
page = await browser.get_current_page()
current_url = page.url
some_attribute = await page.get_by_text('swwg labs').get_attribute('class')
print(current_url)
return ActionResult(extracted_content = f'The current URL is {current_url} and the attribute is {some_attribute}')


For all i get the same results:

TypeError: Controller.action() missing 1 required positional argument: 'self'
