# Context: Grimoire/Spells Tab "cost.map" Error Fix
|
|
|
|
## Problem Statement
|
|
The Grimoire/Spells tab fails to load with error: `TypeError: e.cost.map is not a function`
|
|
|
|
## Error Analysis
|
|
This error indicates that `e.cost` is not an array (or is undefined) when `.map()` is called. Likely causes:
|
|
1. Spell cost is defined as a single value instead of an array
|
|
2. Missing or malformed spell definitions
|
|
3. Incorrect data structure in spells constants
|
|
4. Legacy store returning incorrect spell state
|
|
|
|
## Key Files to Investigate/Modify
|
|
- `src/components/game/tabs/SpellsTab.tsx` - Spells tab component (likely "Grimoire" tab)
|
|
- `src/lib/game/constants/spells.ts` - Spell definitions
|
|
- `src/lib/game/constants/spells-modules/` - Modular spell definitions
|
|
- `src/lib/game/stores/skillStore.ts` - Skill state (affects spell unlocking)
|
|
- `src/lib/game/stores/combatStore.ts` - Spell state
|
|
|
|
## Architecture Rules (from AGENTS.md)
|
|
- Use modular stores: import from `src/lib/game/stores/`
|
|
- Spell definitions belong in `src/lib/game/constants/spells.ts` or `spells-modules/`
|
|
- All files must stay under 400 lines
|
|
- No legacy store references
|
|
|
|
## Debugging Steps
|
|
1. Find where `.map()` is called on spell cost in SpellsTab.tsx
|
|
2. Check spell definition structure for `cost` field
|
|
3. Verify spell cost is always an array (even for single cost)
|
|
4. Check if cost is properly initialized for all spells
|
|
5. Ensure spells are correctly loaded from constants
|
|
|
|
## Expected Outcome
|
|
- Spells tab loads without errors
|
|
- All spell costs are properly formatted as arrays
|
|
- Spell definitions are consistent and valid
|
|
- Regression test added to `src/lib/game/stores/__tests__/index-tests/spell-cost.test.ts`
