Hybrid Retriever With Bm25 Chroma

Hello guys, I'm having some problems indexing using chroma, when i try to index more than 52 nodes (chunk_size = 1024, chunk_overlap = 128) the program just stops after finishing the embeddings, i'm using the example provided in the site https://docs.llamaindex.ai/en/stable/examples/retrievers/bm25_retriever/#hybrid-retriever-with-bm25-chroma
