1.6.6

⚙️ Patch 1.6.6 — Repricer stability, profit accuracy and UI fixes

🚀 Summary

  • Fix Shopify expected profit to use the real margin model instead of price − buy_price.
  • Run FBM recalculations in a background thread so bulk SP-API work no longer blocks other API requests.
  • Surface SP-API fee failures as proper article errors instead of silent fallback values.
  • Fix UVP removal, FBM export persistence, and article table header alignment.

✨ Improvements

  • Backend (Shopify):
  • expected_profit now uses the same net-revenue formula as price calculation (VAT, provision, fixed fee, package cost).
  • Backend (FBM):
  • FBM recalculation runs in a worker thread (same pattern as FBA), keeping the server responsive during long batch recalcs.
  • SP-API FeesEstimate failures raise SpApiFeeEstimateError and set per-country pricing errors plus article status=error with the real message (e.g. invalid/missing ASIN for SKU).
  • UVP export persists DE.ignore=true via deep-copy of international_pricing so JSONB updates are reliably saved.
  • Backend (UVP):
  • DELETE /{sku}/uvp accepts an optional body (channel flags) and clears min_uvp / max_uvp correctly.
  • Frontend:
  • Kaufland article table headers aligned with body columns (listing/min/max price, buybox, expected profit).
  • FBM table headers renamed to Min Price / Max Price with corrected column spans.

🐛 Bug Fixes

  • Fixed FBM export DetachedInstanceError by re-fetching FBMDetails by ID after async Plenty/Sellerlogic calls.
  • Fixed DELETE UVP returning 422 because the frontend sent no request body.
  • Fixed sync_details_prices possibly using price_value before assignment when Plenty returned an unsupported or empty price entry.
  • Fixed misleading SP-API logs that claimed “returning fallback values” while still producing incorrect profit data.
