Can't solve this redirect :(

Hi, I can't solve how this .htacces rule should be rewritten :( could someone please try to help me

in .htaccess
RewriteRule ^filters$ index.php?controller=filters [L,QSA]

Have tried the following rwdirects but all gives me the "The page isn’t redirecting properly"

rewrite ^filters$ /index.php?controller=filters last;
rewrite ^/filters/$ /index.php?controller=filters last;
rewrite ^/filters$ /index.php?controller=filters last;

Non of the above works, but checked it on apache, and there the rule works perfectly
