Cannot create property 'chatHistory' on string '' [BUG]

[ms6rb]

Describe the bug I'm getting this error Cannot create property 'chatHistory' on string '' in the chat on a fresh install.

To Reproduce Steps to reproduce the behavior: 1- Install 2- Add OpenAI agent and MRKL agent for LLMs (any agent actually) 3- Chat with the bot 4- See error in the chat Cannot create property 'chatHistory' on string '' 5- See error in the browser console:

xhr.js:220 
POST http://localhost:3000/api/v1/internal-prediction/7e589d54-11e0-4ee0-b0c1-7a598c885163 500 (Internal Server Error)

Expected behavior I expected to get a response from the bot.

I'm having the same issue

Hi @eitanwaxman,

could you share a screenshot of your flow?

[eitanwaxman]

@chungyau97 My flow looked exactly like the one above. I did find an answer on the discord - apparently you need to use a Chat LLM Model with a Chat agent. (I was trying to use a regular one). - Now it's working

Thanks!
