Issue when scraping from VK Channels / Groups

Hi!

I'm having some issues with scraping from VK channels / groups.

Currently, I'm getting the following:

Scraping from users is fine - no errors being received. But I'm unsure whether I am invoking the wrong command as VK groups channels do not have a ID string.

Thanks in advance.
