Error: One input key expected got ['query', 'context', 'handle_keys']

I am getting this message from the chat window.

I tried specifying the values in chat_inputs string but this seems to have made no difference.

chat_inputs='{"query":"","context":"","handle_keys":""}'

This only happened after I added ConversationWindowBuffer to the flow. The "context" is coming from a text file loader and I believe that is also where the "handle_keys" is coming from.

This flow works fine in LangFlow so clearly I am doing something wrong with the UI config.

I should probably also include a clip from my Prompt Template. You can see here I am putting the context variable into the template. context should be loaded from the TextLoader.

Context: {context} Chat History: {chat_history} Human: {query} AI:
