[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

PytubeError: Exception while accessing title of https://youtube.com/watch?v=FD-yp57VbmQ. Please file a bug report at https://github.com/pytube/pytube
Traceback:
    File "path_to_crewai_tools/youtube_video_search_tool.py", line XX, in __init__
        self.add(youtube_video_url)
    File "path_to_pytube/__main__.py", line 346, in title
        self._title = self.vid_info['videoDetails']['title']
    KeyError: 'videoDetails'

Environment

• crewai version: 0.51.1
• pytube version: 15.0.0
• Python version: 3.11.9
• Operating System: macOS Sequoia 15.1

Expected behavior

YoutubeVideoSearchTool should retrieve information from the specified YouTube video URL without errors.

This seems to be an issue stemming from PyTube. I presume this is a downstream issue from YouTube changing some of their code. We'll track and implement a patch. Here's a related issue on PyTube https://github.com/pytube/pytube/issues/2074

This solution mentioned in https://github.com/pytube/pytube/issues/2074 worked for me

Step 1) Find where pytube is installed in your local

import pytube import os print(os.path.dirname(pytube.file))

Step 2) Go to this location where package related files are saved, open main.py and modify the code with below

`def vid_info(self): """Parse the raw vid info and return the parsed result.

:rtype: Dict[Any, Any]
"""
if self._vid_info:
    return self._vid_info

innertube = InnerTube(client='WEB', use_oauth=self.use_oauth, allow_cache=self.allow_oauth_cache)

innertube_response = innertube.player(self.video_id)
self._vid_info = innertube_response
return self._vid_info`
