[BUG] PytubeError when using YoutubeVideoSearchTool with a specific YouTube video URL

[naoki1213mj]

Description

Summary

When attempting to use YoutubeVideoSearchTool with a specific YouTube video URL, a PytubeError occurs. This error is raised by pytube while trying to access the video title. The error message suggests a missing videoDetails field in the YouTube response, which causes a KeyError. This issue may be related to recent changes in YouTube’s data structure or a limitation within pytube.

Steps to Reproduce

1. I used the following code to initiate a YoutubeVideoSearchTool instance with a specified YouTube video URL:

   from crewai_tools import YoutubeVideoSearchTool
   
   youtube_video_url = "https://www.youtube.com/watch?v=FD-yp57VbmQ"
   youtube_video_search_tool = YoutubeVideoSearchTool(youtube_video_url=youtube_video_url)

2. When this code runs, it raises a PytubeError with a KeyError: 'videoDetails', which prevents YoutubeVideoSearchTool from working with this video.

Error Message

        self._title = self.vid_info['videoDetails']['title']
    KeyError: 'videoDetails'
