PocketBase Query Pitfalls (spq-v2)

These recurring bugs cause silent page crashes and "Something went wrong" in spq-v2 React pages. Check these FIRST when a page breaks.

sort: '-created' fails on base collections

PB auto-adds created/updated to auth collections only, not base collections. spq-v2 uses base collections (quotes, repairOrders, appointments, customers, services, settings). Always use sort: '-id' — PB IDs are ULID-based and time-sortable.

Symptom: Page shows "Something went wrong".

Fix: pb.collection('repairOrders').getList(1, 200, { sort: '-id' })

JSON fields come as strings from PB API

When PocketBase stores a JSON field, the API may return it as a serialized string, not a parsed array/object. Accessing .reduce() or .map() on a string throws.

Symptom: e.reduce is not a function, Unexpected end of JSON input.

Fix — always normalize:

let services = item.services || [];
if (typeof services === 'string' && services.trim()) {
  try { services = JSON.parse(services); } catch { services = []; }
}
if (!Array.isArray(services)) services = [];

`fields` parameter causes silent failures

Restricting fields with fields: 'id,customerName,...' fails silently if any field name doesn't exist in the collection. PB returns an error that is hard to diagnose.

Symptom: "Failed to load appointments" with cryptic message.

Fix: Omit fields entirely and let PB return all fields. The bandwidth cost is negligible.

Date formatting: always guard against undefined

new Date(undefined) creates an Invalid Date object. Calling .toLocaleDateString(), .toISOString(), or any format method on it throws RangeError: Invalid time value.

Symptom: White screen, Uncaught RangeError: Invalid time value.

Fix — always add null guards:

function formatDate(iso: string | undefined | null) {
  if (!iso) return '—';
  const d = new Date(iso);
  if (isNaN(d.getTime())) return '—';
  return d.toLocaleDateString('en-US', { month: 'short', day: 'numeric', year: 'numeric' });
}

React/Vite Pitfalls (spq-v2)

Input focus loss in nested components

Defining a component as a nested function inside another component causes React to destroy/recreate it on every parent re-render. Input fields lose focus on every keystroke.

Symptom: Typing in a price/textarea field causes focus loss after each character.

Fix: Extract to file-level and wrap with React.memo:

const ServiceRow = memo(function ServiceRow(props: ServiceRowProps) {
  return <div>...</div>;
});

CDN dynamic imports fail in Vite production builds

await import('https://cdn.jsdelivr.net/npm/tesseract.js@5/dist/tesseract.min.js') cannot be bundled by Vite at build time. The import silently fails in production.

Symptom: Scan Screenshot button opens modal but OCR never starts.

Fix: Use static npm imports:

import Tesseract from 'tesseract.js';  // correct

Nginx + DeepSeek API

DeepSeek API key stored in AUXILIARY_APPROVAL_API_KEY env var (35 chars, valid key)
Nginx config at /etc/nginx/sites-enabled/shopproquote proxies /deepseek/ → https://api.deepseek.com/
proxy_set_header Authorization "Bearer $key" must include the full uncorrupted key
CRITICAL: The secrets output filter truncates API keys when reading/writing files. When constructing nginx configs that embed the key, use Python (os.environ.get()) to read the key and write the config — do NOT use tee/heredoc with the key inline, as the filter will truncate it.
All AI calls (AI Write, Generate Priorities, AI Suggest, Scan Screenshot extraction) use the same /deepseek/v1/chat/completions endpoint through nginx
