Airflow try number issue

I have encountered an error during testing , does anyone have any lead on this.

Code:

relative_path = self._render_filename(ti, ti.try_number)

Error:

AttributeError: 'str' object has no attribute 'try_number
Solution

  • This error in Airflow usually happens because the BaseHook class can no longer receive an str parameter[1], only a ti (TaskInstance) [2]. You can simply create the BaseHook without providing any parameters like:

    my_hook = BaseHook()
