Error 13119 — Quantity unavailable or invalid

Quantity value in your feed is invalid (negative, zero on a non-discontinued product, or non-integer).

Inventory sync issues — your storefront's stock drops to zero but you're updating Amazon to a positive number, or vice-versa.

1. Confirm quantity is a non-negative integer in your feed.
2. Use 0 for out-of-stock, positive integer for in-stock.
3. Don't submit negative quantities or floats.
4. Sync inventory at least daily, hourly for fast-moving products.

• Floating-point quantities (4.5 units) — round to integer
