Error message

giftee_purchase.errors.full_messages[0]

What it means

Gift checkouts build a second, recipient-side purchase (perceived_price_cents forced to 0, is_gift_receiver_purchase true) and run process! on it. If that giftee purchase ends up with validation errors, the first full message is re-raised as PurchaseInvalid - so the message text is whatever the underlying model validation produced, not a fixed string. This is a passthrough of giftee_purchase.errors.full_messages[0].

Solutions

1. Inspect giftee_purchase.errors (all messages, not just the first) in a console or debugger to identify the failing validation.
2. Fix the offending field - most commonly the giftee email - and resubmit.
3. Integrators: log the full errors object server-side when this passthrough fires, since the raised message alone may hide additional errors.

Example fix

# before: only the first error surfaces
raise Purchase::PurchaseInvalid, giftee_purchase.errors.full_messages[0] if giftee_purchase.errors.present?

# after (debugging aid): log everything, then raise the first
Rails.logger.warn("giftee purchase invalid: #{giftee_purchase.errors.full_messages.join(', ')}")
raise Purchase::PurchaseInvalid, giftee_purchase.errors.full_messages[0] if giftee_purchase.errors.present?

giftee = gift_params[:giftee_id].present? ? User.alive.find_by_external_id(gift_params[:giftee_id]) : User.alive.by_email(gift_params[:giftee_email]).last
raise ArgumentError, 'giftee user not found' if gift_params[:giftee_id].present? && giftee.nil?

begin
  purchase, error = Purchase::CreateService.new(product:, params:, buyer:).perform
rescue Purchase::PurchaseInvalid => e
  # passthrough of giftee_purchase model errors - log context, surface the message
  Rails.logger.warn("giftee purchase invalid: #{e.message}")
  render_checkout_error(e.message)
end

When it happens

Trigger: Gift flow completes create_gift, giftee_purchase.process! runs, and giftee_purchase.errors is non-empty afterwards - e.g. recipient-side email or purchase-model validations failing on the zero-priced receiver purchase.

Common situations: Giftee email that fails user/purchase validations; giftee account state issues (deleted/alive checks in giftee_purchaser lookup); any recipient-side model validation tripping during process!.
