To resolve the "400 Bad Request" error you're encountering with the Langflow JS API, ensure that you do not pass both an input_value and a tweak with the same name for a component when the input_type is "chat" or "text". The API raises an error if both are provided for the same component.

Here's a brief explanation of the relevant code logic:

• The API checks if both an input_value and a tweak with the same name are provided for a chat or text input. If so, it raises an InvalidChatInputError with the message: "If you pass an input_value to the chat input, you cannot pass a tweak with the same name."

To fix this, adjust your API request payload to ensure that you are not including both an input_value and a tweak for the same component when using "chat" or "text" as the input_type ^[1][2].
