Rails - find_by_sql with heredoc raises error

I have this simple SQL in a heredoc
sql = <<-SQL
SELECT SUM(price) as total_price,
SUM(distance) as total_distance,
TO_CHAR(date, 'YYYY-MM') as month
FROM Rides
WHERE user_id = #{current_user.id}
GROUP_BY month
SQL
and a find_by_sql(sql) call
Ride.find_by_sql(sql).each do |row|
"#{row.month}: { total_distance: #{row.total_distance}, total_price: #{row.total_price} }"
end
and it raises error:
ActiveRecord::StatementInvalid: PG::SyntaxError: ERROR: syntax error at or near "GROUP_BY"
LINE 6: GROUP_BY month
^
: SELECT SUM(price) as total_price,
SUM(distance) as total_distance,
TO_CHAR(date, 'YYYY-MM') as month
FROM Rides
WHERE user_id = 1
GROUP_BY month
As you can see, it interpolates the user_id fine so the issue is not in interpolation.
It works if I assign this SQL to a variable as as string, like so:
str = "select sum(distance) as total_distance, sum(price) as total_price, to_char(date, 'YYYY-MM') as month from rides where user_id = #{ current_user.id } group by month"
What is the problem with heredoc?
