Drupal 8 and Rules

Good day!

I cannot configure Rules to send email notifications to the node author about new comments on that node.

I googled... but there is no good documentation for the module specifically for Drupal 8... only for 7...

When creating an action on the event of saving new content, an error occurs: "An unexpected error occurred..."

Or maybe there are other modules with such functionality for Drupal 8? Everything I find is for 7...

Thank you!
