Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

vectorstore = Chroma.from_documents(
    documents=doc_splits,
    collection_name="rag-chroma",
    embedding=GPT4AllEmbeddings(),
)

Description

I am trying to use langchain to implement RAG. However, a bug occured as I was building vectorDB with GPT4AllEmbeddings. The code and bug are shown above.
