[Bug]: <title>Error embedding chunk {'OpenAIEmbedding': "'NoneType' object is not iterable"}
Describe the bug
I have finished the pipeline with llm and ebedding of ollama. However, when I tried to query: python -m graphrag.query --root pg18v8 --method local "describe the types of impact craters"
The error message is:

Thank you for replaying. I succeed in finishing the pipeline, but I am looking for solution for the bug when query with local models.
Hi @hongyispace Did you find a solution to fix the bug when local query with local model?
Hi I have hacked it via changing the code in graphrag/query/llm/oai/openai.python "chunck_text" method: (remove token encode, because the local llm just can embed text instead of encoded ones)
def chunk_text( text: str, max_tokens: int, token_encoder: tiktoken.Encoding | None = None ): """Chunk text by token length.""" # if token_encoder is None: # token_encoder = tiktoken.get_encoding("cl100k_base") # tokens = token_encoder.encode(text) # type: ignore # chunk_iterator = batched(iter(tokens), max_tokens) chunk_iterator = batched(iter(text), max_tokens) yield from chunk_iterator
