incomplete_pages is currently required argument and app does not run without it. You have two options.

1. pass in empty list incomplete_pages=[] or
2. make incomplete_pages optional:

• Step 1: add import from dataclasses import dataclass, field
• Step 2: replace ChartGroup` dataclass with the below code (line 34 in this file)
  import

@dataclass
class ChartGroup:
    """Represents a group of charts like "Deviation"."""

    name: str
    pages: list[vm.Page]
    intro_text: str
    incomplete_pages: list[IncompletePage] = field(default_factory=list)  # not required if ChartGroup complete
    icon: str = ""  # ALL_CHART_GROUP is the only one that doesn't require an icon.
