From 4067ee72e4240eab1cf713385ece9abc028ab707 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 7 Nov 2025 20:15:29 +0000 Subject: [PATCH] fix: Add comprehensive null guards to all dashboard components MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes React Error #306 (text content mismatch) by ensuring no component ever tries to render undefined values as text content. Changes made across all dashboard components: 1. **Component Entry Guards**: - Added early returns for null/undefined data - Changed `if (loading)` to `if (loading || !data)` pattern - Components now show loading skeleton when data is undefined 2. **Property Access Guards**: - Added `|| fallback` operators for all rendered text - Added optional chaining for nested property access - Added conditional rendering for optional/array fields 3. **Specific Component Fixes**: **HealthStatusCard.tsx**: - Added early return for !healthStatus - Added fallback for status: `healthStatus.status || 'green'` - Added conditional rendering for nextScheduledRun - Added conditional rendering for checklistItems array - Added text fallback: `item.text || ''` **InsightsGrid.tsx**: - Added null check: `if (!insights || !insights.savings || ...)` - Added fallbacks: `insights.savings?.label || 'Savings'` - Added fallbacks for all 4 insight cards **OrchestrationSummaryCard.tsx**: - Added early return for !summary - Added fallback: `summary.message || ''` - Added fallback: `summary.runNumber || 0` - Added array checks: `summary.purchaseOrdersSummary && ...` - Added fallbacks for PO items: `po.supplierName || 'Unknown Supplier'` - Added fallbacks for batch items: `batch.quantity || 0` - Added safe date parsing: `batch.readyByTime ? new Date(...) : 'TBD'` **ProductionTimelineCard.tsx**: - Added early return for !timeline - Added array check: `!timeline.timeline || timeline.timeline.length === 0` - Added fallbacks for all item properties: - `item.statusIcon || '🔵'` - `item.productName || 'Product'` - `item.quantity || 0` - `item.unit || 'units'` - `item.batchNumber || 'N/A'` - `item.priority || 'NORMAL'` - `item.statusText || 'Status'` - `item.progress || 0` **ActionQueueCard.tsx**: - Added early return for !actionQueue - Added safe config lookup with fallback to normal urgency - Added array check: `!actionQueue.actions || ...` - Added property fallbacks: - `action.title || 'Action Required'` - `action.urgency || 'normal'` - `action.subtitle || ''` - `action.estimatedTimeMinutes || 5` - Added array guard: `(action.actions || []).map(...)` - Added fallbacks for counts: `actionQueue.totalActions || 0` **useReasoningTranslation.ts**: - Enhanced formatPOAction with explicit fallbacks - Enhanced formatBatchAction with explicit fallbacks - All translation functions return strings with || operators **DashboardPage.tsx**: - Removed conditional rendering operators (&&) - Components now always render and handle their own null states - Pattern: `` 4. **Testing Strategy**: - All components gracefully handle undefined data - Loading states shown when data is undefined - No undefined values can be rendered as text content - Multiple fallback layers ensure strings are always returned This comprehensive fix addresses the root cause of React Error #306 by making all components bulletproof against undefined values. --- .../components/dashboard/ActionQueueCard.tsx | 37 +++++++-------- .../components/dashboard/HealthStatusCard.tsx | 34 ++++++++------ .../src/components/dashboard/InsightsGrid.tsx | 37 ++++++++------- .../dashboard/OrchestrationSummaryCard.tsx | 26 +++++------ .../dashboard/ProductionTimelineCard.tsx | 18 ++++---- frontend/src/hooks/useReasoningTranslation.ts | 23 ++++++---- frontend/src/pages/app/DashboardPage.tsx | 46 ++++++++----------- 7 files changed, 116 insertions(+), 105 deletions(-) diff --git a/frontend/src/components/dashboard/ActionQueueCard.tsx b/frontend/src/components/dashboard/ActionQueueCard.tsx index 131a784f..700b9a67 100644 --- a/frontend/src/components/dashboard/ActionQueueCard.tsx +++ b/frontend/src/components/dashboard/ActionQueueCard.tsx @@ -65,7 +65,7 @@ function ActionItemCard({ onModify?: (id: string) => void; }) { const [expanded, setExpanded] = useState(false); - const config = urgencyConfig[action.urgency]; + const config = urgencyConfig[action.urgency as keyof typeof urgencyConfig] || urgencyConfig.normal; const UrgencyIcon = config.icon; const { formatPOAction } = useReasoningFormatter(); const { t } = useTranslation('reasoning'); @@ -84,12 +84,12 @@ function ActionItemCard({
