Value Error: Naive DateTime Disallowed

[NishaDeepak]

Airflow version used: 2.10.4

Am trying to build a code to handle the data intervals. I want the time to be the same as dag schedule time. For example,

Consider the dag run is on 2025-07-13 at 11:00:00 then the data intervals should be:

start: 2025-07-12 11:00:00
end: 2025-07-13 11:00:00

Attached are the pugin and dag python scripts as txt files.

Value Error: Naive DateTime Disallowed
The above error shows up due to line: next_start = (next_day,self._schedule_time) of Custom_Timetable.py

Could you please suggest how I can fix this error.
