Error in embedding

[chiauho]

Hi, I ran into error while embedding using library.install_new_embedding function. Here's a simple code I copied from fast start example 2:

LLMWareConfig().set_active_db('sqlite')
LLMWareConfig().set_vector_db('chromadb')
library = Library().load_library('hr_documents')
embedding_model = 'all_mpnet-base-v2'
vector_db = LLMWareConfig().get_vector_db()
library.install_new_embedding(embedding_model_name=embedding_model, vector_db=vector_db, batch_size=100)

The error occurred at the last line of the code. Here's the error (a bit long, so I only show the last 3 lines. I've uploaded the complete errormsg text):

File "C:\Users\xx_user\AppData\Local\miniconda3\envs\yy_project\Lib\site-packages\chromadb\api\types.py", line 800, in validate_documents
raise ValueError(f"Expected document to be a str, got {document}")
ValueError: Expected document to be a str, got 1 in add.

Please note that the library was already created using fast start example 1 and I was able to do a text query without issue.

Appreciate any help I can get. Thank you.
