Below are my .env settings
CHROMA_COLLECTION=chromadb-hr-docs
CHROMA_HOST=http://localhost:8000
CHROMA_PORT=8000

successfully installed chromadb on my local mac and able to run by using below command
chroma run --host localhost --port 8000 --path chromadb-docs

But on running the 'npm run generate' command I am getting below error

Using 'openai' model provider

Started parsing the file under job id 1f3497ad-93de-4389-954b-60efba609ff2
