Code Review

I found 4 critical syntax errors in this PR that will prevent the module from importing:

---

Issue: Invalid Python 3 exception syntax (4 occurrences)

File: backend/src/services/calendar/database/operations.py

Lines: 2006, 2573, 2729, 2742

Problem: The PR changes the exception handling syntax from except (ValueError, TypeError): to except ValueError, TypeError: (removing the parentheses). This is invalid Python 3 syntax and will cause a SyntaxError when the module is imported.

In Python 3, you must use parentheses to catch multiple exception types:

• ✅ Correct: except (ValueError, TypeError):
• ❌ Invalid: except ValueError, TypeError:

The comma syntax without parentheses was Python 2 syntax for binding the exception to a variable (equivalent to except ValueError as TypeError: in Python 3).

Impact: The module will fail to import, crashing the calendar service at startup.

   Lines 2005 to 2009 in fb3994f

   	except ValueError, TypeError:
   	start_dt = now_local.replace(minute=0, second=0, microsecond=0) + timedelta(
   	hours=1
   	)

   except ValueError, TypeError:  # ❌ Should be: except (ValueError, TypeError):

   	pass

   except KeyError, ValueError:  # ❌ Should be: except (KeyError, ValueError):

   	elif start_dt.tzinfo is None:
   	start_dt = start_dt.replace(tzinfo=dt_timezone.utc)

   except KeyError, ValueError:  # ❌ Should be: except (KeyError, ValueError):

4. Line 2742:

   Lines 2741 to 2745 in fb3994f

   	end_dt = end_dt.replace(tzinfo=end_tz)
   	except KeyError, ValueError:
   	end_dt = end_dt.replace(tzinfo=dt_timezone.utc)
   	elif end_dt.tzinfo is None:
   	end_dt = end_dt.replace(tzinfo=dt_timezone.utc)

   except KeyError, ValueError:  # ❌ Should be: except (KeyError, ValueError):

Fix: Restore the parentheses around the exception tuples at all 4 locations.

The other changes in this PR (middleware.py, routes.py, environment.py) look correct.

Summary

Fixed all 4 Python 3 exception syntax errors in backend/src/services/calendar/database/operations.py by adding the missing parentheses around exception tuples:

• Line 2006: except ValueError, TypeError: → except (ValueError, TypeError):
• Line 2573: except KeyError, ValueError: → except (KeyError, ValueError):
• Line 2729: except KeyError, ValueError: → except (KeyError, ValueError):
• Line 2742: except KeyError, ValueError: → except (KeyError, ValueError):

The module will now import correctly without syntax errors.
