LLMContextFrame, a validLLMContextcan contain anLLMSpecificMessageafter its latest user message. Pipecat 1.8 returns that object fromget_messages(), but it has no.get()method. The scan raisesAttributeError;process_framethen emits an error and does not forward the context frame. Check for a standard dict message before reading its role.

- Line 115: Update the context-building flow before `self.push_frame(frame,
direction)` so retrieved text is placed in a provider-neutral part of the query
context before the user query, rather than appended as a system message; then
forward the frame with the retrieval text associated with that query.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep retrieved text associated with the query for Gemini.
When this universal context frame goes to Pipecat 1.8’s Gemini adapter, context.add_message({"role": "system", ...}) has appended the retrieved text after the user query. The adapter converts non-initial system messages to user messages. Gemini therefore receives the retrieved text as a later user turn, not as system context for the query. Place the retrieval text in a provider-neutral part of the query context before forwarding the frame. (github.com)
