ClickTool Should Better Handle Hallucinated and Invisible Links

[cancan101]

As of now if a hallucinated link is handed to the ClickTool, it will wait for 30 seconds and then fail. Instead it should generate a message that is added to the prompt along the lines of: "I was unable to find that element. Could you suggest another approach?"

In addition it might be handed an element that is invisible (or for which there are multiple matching elements the first of which is invisible). Similarly, the Tool will wait until the element becomes visible, which may never happen (e.g. for mobile pages where some of the nav buttons are hidden). There are a few options here, one is to use force=True when clicking. Other options are to filter to visible elements using one of the approaches in: microsoft/playwright#2370 or https://www.programsbuzz.com/article/playwright-selecting-visible-elements.

Thank you for the recommendation! This is a great suggestion. Would you be interested in drafting a PR? i'd be happy to help out

I put up an initial PR.
The force option doesn't work if the element is not visible.

I wonder if get_elements should be modified to return visible elements.

Hi, @cancan101! I'm Dosu, and I'm helping the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.

Based on my understanding, the issue you raised was about the ClickTool failing when given a hallucinated link and waiting indefinitely for invisible elements to become visible. There have been some discussions in the comments, and it seems that a possible solution is to use the force=True option when clicking or filtering for visible elements.

It looks like you have already put up an initial PR, and there was a suggestion from a user named vowelparrot to modify the get_elements function to return visible elements.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you for your contribution!
