Search script on YouTube from Google API V3. I have the error (urllib.error.HTTPError: HTTP Error 404: Not Found)

I am trying to test this script in Google Python to do searches on YouTube. The code I have removed from here:

link

I had to make a couple of changes to make it work with Python 3

The only thing I've done is add parentheses to all print () .

Include this module import urllib.request .

and change these two lines

  freebase_url = FREEBASE_SEARCH_URL % urllib.parse.urlencode(freebase_params)
  freebase_response = json.loads(urllib.request.urlopen(freebase_url).read())

That they were like this before

 freebase_url = FREEBASE_SEARCH_URL % urllib.urlencode(freebase_params)
 freebase_response = json.loads(urllib.urlopen(freebase_url).read())

But he is giving me this error

urllib.error.HTTPError: HTTP Error 404: Not Found

The error comes to me in any way that executes the scritp (with arguments and without them). I'm trying to execute it like this:

py -3 C:\Users\ivan\Desktop\Codigos_YouTube-buscar\buscar_freebase.py --query="Barsa Madrid" --type="playlist"

The following is the modified full code:

Apparently the error is related to this line

freebase_response = json.loads(urllib.request.urlopen(freebase_url).read()

But I'm not sure what the reason may be. Any questions?
