hey guys, I'm trying to generate a graph index following the chatbot example but I'm having a weird issue. In ComposableGraph from_indices, I'm getting the exception that the index variable does not contain an index_struct property, and it doesn't because it's just a string there, but I am passing in valid indexes as can be seen on the children_indices variable
one issue I see is when constructing the graph, on line 65, you probably want to do list(index_set.values()) assuming that index_set is a dictionary (it looks like it is?)
