run graph codegen with this abi
What is the expected behavior?
should support tuple[][]

Comienza ejecutando graph codegen con la ABI mostrada en el issue y reproduce el fallo para el argumento tuple[][]. Rastrea el punto de entrada de conversión de tipos ABI que informa de la conversión no compatible y, a continuación, verifica que la generación de código se realiza correctamente para arrays de tuplas anidados sin introducir regresiones en los casos ABI existentes.
