Overview

Agent Fallback are mechanisms that allow you to gracefully handle script execution failures without any additional code:
agent_fallback.py
from notte_sdk import NotteClient, actions

notte = NotteClient()
url = "https://www.linkedin.com/feed/"
company_name = "nottelabs"

# scrape all new posts (post url, date, title, content) from the company page on LinkedIn
with notte.Session() as session:
	session.execute(actions.Goto(url=url))
	# spin up agent fallback if the search for the company name fails
	with notte.AgentFallback(session,
		task=f"Open the company page for {company_name}. Fail if user is not logged in.") as agent:
		# search for the company name
		session.execute(actions.Fill(selector="internal:role=combobox[name=\"Search\"i]", value=company_name))
		# press enter to search
		session.execute(actions.PressKey(key="Enter"))
		# click on the company link
		session.execute(actions.Click(selector=f"internal:role=link[name=\"{company_name}\"s] >> nth=0"))
	# open the post tab on the company page
	session.execute(actions.Click(selector="internal:role=link[name=\"Posts\"i]"), raise_on_failure=False)
	data = session.scrape(instructions="scrape all new posts (post url, date, title, content)")
	print(f"Scraped data: {data}")
They ensure your scripts always terminate successfully even if the website changes or something unexpected happens.
