KeyError: 'function' not found

[RishikMani]

In the file programs.py inside the function build_subtree, the script tries to create a new key as follows:

def list_to_tree(program_list):
    def build_subtree(cur):
        return {
            'function': cur['function'],
            'value_inputs': [x for x in cur['value_inputs']],
            'inputs': [build_subtree(program_list[i]) for i in cur['inputs']],
        }
    return build_subtree(program_list[-1])

I have tried generating new images with new questions, but never I see the key function in cur[function]. Has it happened with anyone else? Were you able to resolve it?

ya this happened to me -- I'm vaguely thinking it's a versioning issue. I changed the keyword "function" to "type" and that seemed to fix it
