After the program ran to Data structures and interface definitions:, an error occurred. May I ask what caused it?

`## Data structures and interface definitions:

you need to define the customized OUTPUT_MAPPING or follow the predefined OUTPUT_MAPPING

This problem actually comes from the poor Instruction Following of gpt-3.5-turbo. gpt-4 basically does not have this problem
