New event Calendar creation using YAML

I would like to automate the creation of a calendar event as of below. I would like to use a local calendar not Google. This is the error I’m getting. What am I missing? I did some google searching and I did not find anything on this topic.

extra keys not allowed @ data[‘end_time’]. Got None extra keys not allowed @ data[‘start_time’]. Got None extra keys not allowed @ data[‘title’]. Got None required key not provided @ data[‘summary’]. Got None

service: calendar.create_event
data:
entity_id: calendar.testing_calendar
title: testing
description: Manually triggered calendar event
start_date: “{{ now().date() }}”
start_time: “{{ now().strftime(‘%H:%M:%S’) }}”
end_date: “{{ (now() + timedelta(hours=1)).date() }}”
end_time: “{{ (now() + timedelta(hours=1)).strftime(‘%H:%M:%S’) }}”

I have it figured out for users that have the same issue as mine

service: calendar.create_event
data:
entity_id: calendar.testing_calendar
summary: testing
description: Manually triggered calendar event
start_date_time: ‘{{ now().strftime(“%Y-%m-%d %H:%M:%S”) }}’
end_date_time: ‘{{ (now() + timedelta(seconds=10)).strftime(“%Y-%m-%d %H:%M:%S”) }}’
