GetChatAdministrators returns []ChatMember, where ChatMember is a sealed-interface union. The codegen template emitted the generic client.Call[..., []ChatMember] for it — encoding/json cannot unmarshal a slice of an interface (no discriminator-aware path), so every real response from Telegram failed at the parse step: telegram: parse: json: cannot unmarshal api.ChatMember into Go struct field Result[[]ChatMember].Result of type api.ChatMember Fix is in cmd/genapi/methods.tmpl: add a third branch alongside the existing single-union branch. When a method returns []<union>, emit CallRaw + json.Unmarshal into []json.RawMessage + per-element Unmarshal<Union>(e). Mirrors what GetChatMember (single-element) already does, applied uniformly so any future slice-of-union method Telegram introduces inherits the right shape. Survey of v1.1.1 across all 23 sealed-interface unions confirms GetChatAdministrators was the only broken site; the fix regenerates just that one method body. New regression tests in api/getchatadministrators_test.go cover the typical admin+owner response and the empty-array case.
