MissingPrice

Error message

Product does not have a price in.

What it means

Thrown by defaultProductsValidation when no variant is supplied and the product itself has no value for the dynamic price field priceIn<CURRENCY>. The error carries an ErrorOptions cause with code 'MissingPrice' and codes [product.id, currency], so callers can inspect error.cause.code to distinguish it from a generic failure. Note the message text 'Product does not have a price in.' is truncated — the currency is not interpolated, but the cause.codes carries it.

Solutions

1. Backfill priceIn<CURRENCY> on the product for the requested currency.
2. Limit checkout currencies to those the product is priced in; hide the product otherwise.
3. Add an admin validation hook requiring all configured currency price fields on product create/update.
4. Inspect error.cause.code === 'MissingPrice' and error.cause.codes to surface a precise message to the customer.

Example fix

// before: product missing priceInEUR
const product = { id: 1, priceInUSD: 2000 } // EUR checkout fails with MissingPrice
// after: backfill the price
const product = { id: 1, priceInUSD: 2000, priceInEUR: 1850 }

function productHasPriceInCurrency(product: Record<string, unknown>, currency: string): boolean {
  const field = `priceIn${currency.toUpperCase()}`
  const v = product[field]
  return typeof v === 'number' ? v > 0 : Boolean(v)
}

if (!productHasPriceInCurrency(product, currency)) {
  const e = new Error(`Product ${product.id} has no price in ${currency}`)
  ;(e as any).cause = { code: 'MissingPrice', codes: [product.id, currency] }
  throw e
}

export function productHasPrice(product: Record<string, unknown>, currency: string): boolean {
  const v = product[`priceIn${currency.toUpperCase()}`]
  return typeof v === 'number' ? v > 0 : Boolean(v)
}

try {
  defaultProductsValidation({ currency, product, quantity })
} catch (err) {
  const cause = (err as Error & { cause?: { code?: string } }).cause
  if (cause?.code === 'MissingPrice') {
    // data gap — backfill or hide the product for this currency
    return { ok: false, reason: 'product-missing-price', productId: product.id, currency }
  }
  throw err
}

When it happens

Trigger: A cart item references a product (no variant) whose priceIn<CURRENCY> field is unset/falsy for the selected currency. Triggered during cart/checkout validation in the product branch.

Common situations: Multi-currency product with prices for some currencies but not the one selected; product created without all configured price fields; a currency added to currenciesConfig without backfilling existing products; data import that omitted price fields; frontend allowing checkout in an unsupported currency for that product.
