To resolve this issue, ensure that all the required environment variables are set in your production environment. In our case, the markdown comes from HTML and is badly structured, we then really on fixed chunk size, making our knowledge base less reliable (one information could be split into two chunks). In the context shared, the 'QAChain' is created using the loadQAStuffChain function with a custom prompt defined by QA_CHAIN_PROMPT.
