How to setup facebook autopost plugin in wordpress?

Question

Facebook

Please help fix the plugin.
WordPress has the Next Scripts: Social Networks Auto Poster plugin. When trying to send a post to facebook, I get this error

Array
(
    [Warning] => 
    [Error] => (#803) Some of the aliases you requested do not exist: sdat.komnatu.v.moskve| Please check what do you have in the "Facebook URL" field.
)

The link to the group looks like this: https://www.facebook.com/groups/sdat.komnatu.v.moskve/
What could be the problem?
