The problem
Trying to add a full day event by automation, both start and end date is required. Using a template, setting a date from a sensor, adding this to both fields.
Tried by setting date manually, same result.
Then receiving this:
Expected minimum event duration of 0:00:01 (2025-11-12, 2025-11-12). Got {'type': 'execute_script', 'sequence': [{'action': 'calendar.create_event', 'data': {'summary': 'hhh', 'start_date': '2025-11-12', 'end_date': '2025-11-12'}, 'target': {'entity_id': ['calendar.xxx']}}], 'id': 439}
Only solution I found is using the time and date fields, adding "00:00:01" after the template. But this does not create a full day event.
Expecting this to give same result as when adding event manually.
