I am trying to remove string from url and it removes also and redirects to new url but it giving 404 i.e. page not found.

My route is :

Route::get('singlepage/{slug}',[WebController::class,'web_pages'])->name('web.pages');

url : https://example.com/singlepage/about-us

result url : https://example.com/about-us

I am trying the code,

RewriteEngine On

RewriteRule ^singlepage/(.*)$ /$1 [L,R=301,QSA]

RewriteRule ^singlepage$ / [L,R=301,QSA]

I don’t understand, where I am missing.
Please help me out.
