Hey @tamdqa! I'm here to help you with any bugs, questions, or contributions you might have. Let's work together to resolve this issue!

The issue you're experiencing with the URL component losing imported URLs in Tool mode after refreshing the UI seems to be related to state persistence. In Langflow, state persistence is typically managed using the useAutoSaveFlow hook, which automatically saves the current state of the flow, including nodes and edges, whenever there are changes ^[1]. However, it appears that this mechanism might not be functioning correctly for the URL component in Tool mode, leading to the loss of input data upon UI refresh.

To address this issue, you might want to check if the useAutoSaveFlow hook is correctly implemented for the URL component in Tool mode. Additionally, ensure that any specific state management logic for the URL component is correctly handling the persistence of input data when switching modes or refreshing the UI. If the problem persists, it may require further investigation or a potential bug fix in the Langflow codebase.

Same issue here. Here's a GIF.

@tamdqa Ok actually it dawned on me "receiving input" is what the user would input in the playground (not hardcoded in flow). So in the playground try asking to scrape a url and you'll see the agent choose to use the url tool.

So @lucaseduoli This could be closed (or maybe consider a small UI enhancement so the + icon isn't there in tool mode when it isn't relevant during flow definition).

Hi! Thanks for the feedback! We just made that change and now the value disappears when enabling tool mode. Indeed the tool mode is made so that the Agent can scrape the URLs by itself. Thanks!
