INVALID_CLIENT: Invalid redirect URL

trying to host my web project , and it doesn't let me to log in when using spotify log-in API

while trying to log in it gives Error: INVALID_CLIENT: Invalid redirect URI,

I have searched in google how to fix this problem a lot of people saying to go to my app on spotify developer dashboard and click edit on my project and put my site as a callback function or my localhost , tried multiple sites but it still doesn't work, btw the redirect URL site is the site I want it to redirect to

 const redirect_url = "https://sbproject.netlify.app/";
 const logout = () => {
 window.localStorage.removeItem("token");
};

return (
 <div className="topnav-items">
   <div className="nav-log">
     <ul className="first-ul">
       {token && (
         <div className="btn">
           <li>
             <a href={redirect_url} onClick={logout}>
               Log-out
             </a>
           </li>
         </div>
       )}
