PartnerReferenceError

Structured per-row error returned by the bulk endpoints. Two levels, distinguished by logistics_unit_code:

Reference-level (index + code + message): failure on the outer reference (e.g. missing product_kinds), none of its logistics units is saved.
Logistics-unit-level (index + code + logistics_unit_code + message): failure on one specific (code, lu_code) row; other logistics units under the same outer reference can still succeed independently.

message
Type: string
required

Human-readable error message.
code
Type: string

Outer code of the failing reference (the partner's own identifier), or the composite code on DELETE.
index
Type: integer

Position of the failing row. On DELETE, the position in the codes array. On POST, use code and logistics_unit_code to match errors: index is not always the reference's position in the request.
logistics_unit_code
Type: string

The failing logistics unit's code (NOT the composite buyer_tag). Populated only when the error is attributable to one specific logistics unit within the outer reference.
