What happened?

Airflow 2 has email_on_failure and other actions that generate links to Airflow 2 UI. This will result in 404 in Airflow 3 once old UI is removed and should be updated. Some of the links I found

airflow/airflow/models/taskinstance.py

Lines 2035 to 2054 in bb56052

	@property
	def log_url(self) -> str:
	"""Log URL for TaskInstance."""
	run_id = quote(self.run_id)
	base_url = conf.get_mandatory_value("webserver", "BASE_URL")
	map_index = f"&map_index={self.map_index}" if self.map_index >= 0 else ""
	_log_uri = (
	f"{base_url}"
	f"/dags"
	f"/{self.dag_id}"
	f"/grid"
	f"?dag_run_id={run_id}"
	f"&task_id={self.task_id}"
	f"{map_index}"
	"&tab=logs"
	)
	if self.logical_date:
	base_date = quote(self.logical_date.strftime("%Y-%m-%dT%H:%M:%S%z"))
	_log_uri = f"{_log_uri}&base_date={base_date}"
	return _log_uri

	base_url = conf.get_mandatory_value("webserver", "BASE_URL")

	)
