Originally created by @MohammedShokr on GitHub (May 20, 2024).

I am deploying a Langchain agent using Langserve and I can call the API from python without any problems but when I open the playground I find the inputs field disabled with an error message "No applicable renderer found."
please note that the input to my agent is a dictionary with two keys; input and chat_history

Here's an image with the error for your reference
