The product needs to be shippable to at least one destinatio

Error message

The product needs to be shippable to at least one destination.

What it means

Raised as Link::LinkInvalid by Link#save_shipping_destinations! when a published (alive?) physical product submits an empty shipping_destinations array (or a single blank string). A published physical product must remain shippable to at least one destination, so clearing all destinations in one save is rejected after the uniqueness check.

Solutions

1. Keep at least one destination row for published physical products — enforce '≥1 row' in the form before submit.
2. If the seller truly wants no shipping, unpublish the product first (the guard only applies to alive? products) or convert it to a non-physical product.
3. Rescue Link::LinkInvalid and surface 'The product needs to be shippable to at least one destination.'

Example fix

# before
link.save_shipping_destinations!([]) # LinkInvalid: published physical product

# after
if link.alive? && link.is_physical && destinations.blank?
  return { error: "The product needs to be shippable to at least one destination." }
end
link.save_shipping_destinations!(destinations)

if link.alive? && link.is_physical && destinations.select { |d| d['country_code'].present? }.empty?
  return { error: 'Published physical products need >=1 destination.' }
end

begin
  link.save_shipping_destinations!(destinations)
rescue Link::LinkInvalid
  render json: { errors: link.errors.full_messages }, status: :unprocessable_entity
end

When it happens

Trigger: Updating a published, alive physical product with shipping_destinations: [] or ['']. Unpublished/deleted products may clear destinations; the guard keys on alive?.

Common situations: Seller deletes every destination row in the shipping table and hits save while the product is live; front-end sends an empty array when the last row is removed; converting product content while forgetting the shipping requirement.
