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

I was facing the same issue, but in my case I was initialising the BaseHook with string

super().__init__("mystring")

removing this "mystring" and initialising the base hook with None works for me.

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()
