Есть уже кем то поднятый сайт

Хочу чтобы был только 1 редирект 301

https non-www trailing slash

В данный момент редиректа, первый на https non-www, второй добавляет слэш в конце. 

Не могу понять откуда берёться слэш, в htaccess этого не прописано

Если добавляю после RewriteEngine

#RewriteCond %{REQUEST_URI} !(.+)/$
#RewriteCond %{REQUEST_FILENAME} -d
#RewriteRule ^(.+)$ https://example.com/$1/ [R=301,L]

#RewriteCond %{REQUEST_URI} /(.+)/$
#RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{REQUEST_FILENAME} !-f
#RewriteRule ^ https://example.com/%1 [R=301,L]

то карточки товаров уходят в бесконечный редирект. 

Так выглядит htaccess в данный момент

RewriteEngine On

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]

RewriteCond %{ENV:HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
