Output from RAG retrieval seems to be missing spaces

[deep41]

I've attached a screenshot from langfuse, seems like when output from RAG retriever seems to be missing spaces between words.

Example 1

Example 2

Might be a potential problem which could cause a degradation in answers from the API.

Found the same storage pattern in mongodb collections.

Maybe the space is quite special and be treated as an escape character during the parsing and storing session to the MongoDB?
