Facing Problem with admin-ajax.php URL - Getting 404 with AJAX call

Question

I am trying to get an ajax response on WordPress, currently, it's showing me a 404 error on the staging server but on dev it's working fine.

I know the problem is due to the use of "forward-slash(/)" in the URL on staging but on dev it's working with or without forward-slash just after admin-ajax.php. Please check the below URL so that you all can understand this in detail

Staging Environment:

URL NOT WORKING(with / ) on staging:

staging/wp-admin/admin-ajax.php/category/movies/?action=get_movies?action=get_my_post

URL WORKING WITHOUT ( / ) on staging:

staging/wp-admin/admin-ajax.php/category/movies/?action=get_my_post

Dev Environment:

URL WORKING(with / ) on staging:

staging/wp-admin/admin-ajax.php/category/movies//?action=get_my_post

URL WORKING WITHOUT ( / ) on staging:

staging/wp-admin/admin-ajax.php/category/movies/?action=get_my_post

as you can see if I remove forward-slash after admin-ajax.php it's working fine on staging but with a forward-slash , it's not working, where is dev environment it's working with our without forward-slash

Ajax code:

function get_movies()
{
   require_once themespro_classifier_addon_template_exsits('movies/templates/grid');
    get_search_tems( $category_for_push ,$paged);
  
    wp_die();  
    
}
