Error on Hugging face- AttributeError: 'OpenAIEmbeddings' object has no attribute 'embedding_ctx_length'

[ailanguageinnovations]

Over the past week I've had a number of projects working fine on Hugging face after duplicating from https://huggingface.co/spaces/hwchase17/chat-your-data-state-of-the-union.
I'm now getting the following error every time I try and interact with the model.

AttributeError: 'OpenAIEmbeddings' object has no attribute 'embedding_ctx_length'

I've just checked again and duplicated your HF project and get the same issue. I can't see any difference between my duplicate of the HF project and yours so not sure what is going on.

There were probably some changes in the last version of LangChain. Using an older version solved the issue for me:
pip install langchain==0.0.86
