v4.1.2 - Calendar Parsing Fixes

Calendar Parsing Bug Fixes

This release fixes critical parsing errors in calendar entities that caused TypeError and KeyError exceptions.

Fixed Issues

KeyError: 'start' in Lessons Calendar (Line 233)

• Fixed missing 'start' and 'end' keys in lesson events
• Now properly constructs datetime objects from 'date' and 'time' fields
• Parses time.from and time.to to create proper start/end datetimes

TypeError: strptime() argument 1 must be str, not datetime.date (Line 335)

• Fixed TypeError when 'date' field is already a date object
• Added isinstance() checks for both str and date types
• Handles both string dates and date objects gracefully

All Calendar Entities

• Added try-except blocks to handle malformed data
• Added logging for debugging parsing failures
• Skips invalid events instead of crashing

Installation

1. Update via HACS (Redownload)
2. Restart Home Assistant
3. Calendar entities should now load without errors

Technical Details

Files Modified:

• calendar.py - Fixed all three async_get_events implementations

Error Messages Resolved:

• KeyError: 'start'
• TypeError: strptime() argument 1 must be str, not datetime.date
• Error handling request from 192.168.70.7
