How to convert select statement to eloquent?

This works in existing website, trying to convert to laravel 5.8

SELECT DATE_FORMAT(created_at, '%M %Y') AS 'article',DATE_FORMAT(created_at, '%m')AS 'm', DATE_FORMAT(created_at,'%Y') AS 'y', COUNT(id) AS 'total' FROM posts GROUP BY DATE_FORMAT(created_at, '%Y%M') ORDER BY m DESC");

I tried:$archives = DB::select("SELECT DATE_FORMAT(created_at, '%M %Y') AS 'article',DATE_FORMAT(created_at, '%m')AS 'm', DATE_FORMAT(created_at,'%Y') AS 'y', COUNT(id) AS 'total' FROM posts GROUP BY DATE_FORMAT(created_at, '%Y%M') ORDER BY m DESC");

Error: SQLSTATE[42000]: Syntax error or access violation: 1055 'amohdb.posts.created_at' isn't in GROUP BY (SQL: SELECT DATE_FORMAT(created_at, '%M %Y') AS 'article',DATE_FORMAT(created_at, '%m')AS 'm', DATE_FORMAT(created_at,'%Y') AS 'y', COUNT(id) AS 'total' FROM posts GROUP BY DATE_FORMAT(created_at, '%Y%M') ORDER BY m DESC)
