[BUG] AttributeError on "FastAPI.get"

[grf53]

Description of changes

• Bug fixes
  • I got an AttributeError during using get operation through the chromadb server running with fastapi.
    This raises by calling .tolist() on the list, so simply removed calling .tolist(), then the bug is fixed.

 File "/my/python/install/localtion/site-packages/chromadb/server/fastapi/__init__.py", line 1128, in get
   cast(Embedding, embedding).tolist()
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'list' object has no attribute 'tolist'

[propel-code-bot]

This PR addresses a bug in the FastAPI server implementation for ChromaDB where an AttributeError was raised during the 'get' operation. The error occurred due to the use of '.tolist()' on a Python list object (embedding), which does not have this method. The code now simply casts the embedding as Embedding without calling '.tolist()', resolving the exception.

[Documentation]

The fix correctly addresses the AttributeError by removing the .tolist() call. However, consider adding a comment explaining that embeddings can be either numpy arrays or lists, and this code handles both cases by simply casting without conversion.

Suggested change

	cast(Embedding, embedding) for embedding in get_result["embeddings"]
	# Embeddings can be numpy arrays or lists - cast handles both
	cast(Embedding, embedding) for embedding in get_result["embeddings"]
