I tried to use ChatGooglePalm with models/chat-bison-001 (default) but error like below:

hmm perhaps there's some setup problem got PaLM. Here's a tutorial on using PaLM on Flowise - https://youtu.be/CfpZ_xZG3bM?si=jeoPF6KtT42mvjtK

Your clip is not using Conversational Retrieval QA Chain and not using ChatGooglePaLM

GooglePaLM is working fine with models/text-bison-001, but ChatGooglePaLM is not working with models/chat-bison-001.
