Describe the bug

After I downloaded the project code from GitHub, I executed the following commands:

poetry install # Install dependency packages poetry run poe index --init --root . # Initialize the project and made adjustments to settings.yaml mkdir input output cache # Since these folders were not created during initialization, I created them myself

After placing a 5k txt file in the input folder, I executed the code: python -m graphrag.index --root .

Error message: In build_index vector_store_type = config.embeddings.vector_store["type"] # type: ignore TypeError: 'NoneType' object is not subscriptable
