Reproduce el problema con el comando cosmwasm-ts-codegen y el esquema mostrados; después, inspecciona wasm-ast-types/main/utils/types.js alrededor de getType y getArrayTypeFromItems. Confirma que el array anidado que contiene la referencia $ref a Uint256 se procesa sin un error de tipo desconocido y vuelve a ejecutar la generación para verificar que finaliza.
