E15055 — WhatsAppInteractiveLimitExceeded

The interactive message exceeds a limit for its kind.

The response names the part at fault. In practice that is the row count: a list carries at most 10 rows across all its sections combined, and it is the one bound the schema cannot state, because it spans the sections rather than sitting inside one. The per-kind lengths are refused by request validation before they reach this code, including the 1024-character body_text that every kind but list is held to. The code is deliberately broader than its one reachable cause, so a bound the schema cannot express in future joins it rather than claiming a code of its own.
