generate questions prompt not configured

Error message

generate questions prompt not configured

What it means

Configuration guard in processQuestionGenerationForKnowledge: the system-level Conversation.GenerateQuestionsPrompt is blank, so Doc2Query-style question generation cannot run. A deployment/configuration defect, not a data problem; the stage refuses to start rather than calling the LLM with an empty prompt.
