Concatenation of list and str in retrieve_relevant_chunks.py

[serhatgktp]

In this line of the example config for pinecone:

NeMo-Guardrails/examples/configs/rag/pinecone/config.py

Line 75 in 5ba7c57

relevant_chunks = []

We see that the relevant_chunks variable is defined as a list.

In the retrieve_relevant_chunks.py file we also observe that relevant_chunks is expected to be a string, hence the attempt to concatenate it with a string.

NeMo-Guardrails/nemoguardrails/actions/retrieve_relevant_chunks.py

Line 80 in 3c955bd

context.get("relevant_chunks", "") + "\n"

Is the custom action in the pinecone config.py file incorrectly configured for the latest version of nemoguardrails, or should retrieve_relevant_chunks.py also account for lists when reading relevant_chunks?

Hi @serhatgktp

Are you getting any specific error when following the readme?

It has been like this at least for a while
