On testing the Search Function I ma getting the Error:

Hey @edwinjosechittilappilly, this is due to YouTube API rate limits. We've requested an increase to our rate limits from YouTube. Alternatively, user can use their own OAuth app while creating the integration (this needs to be created on Composio dashboard) and it will work fine.
