I am trying to add add Search filter in react but I am getting this error

1. I am trying to add Seach filter using the react, and using json data
   I am trying to match it with the search term

2. Below is my code

   const App = () => {
   const [searchTerm, setSearchTerm] = useState([“”])
   const [query, setQuery] = useState(“”);

   useEffect(() => {
   const url = “https://60d075407de0b20017108b89.mockapi.io/api/v1/animals”;

   const fetchData = async () =>
     {
             try
         {
             const response = await fetch(url);
             const json = await response.json();
             console.log([json].query);
             setQuery(json.query);
         }
             catch (error)
         {
             console.log("error", error);
         }
     };
     fetchData();
   

   }, []);

   return (

   <input type=’text’ placeholder=’search….’ onChange={event => { setSearchTerm(event.target.value) }} />

     {
   
             query.filter((val) => {
               if (searchTerm === "s")
         {
             return val
         }
             else if (val.name.toLowerCase().includes(searchTerm.toLowerCase())) {
             return val
         }
         else
             return false
         }).map((val) =>
         {
             return (
             <div className='user' >
             <p>{val.name}</p>
             <p>age: {monthDiff(val.bornAt)} months</p>
   
           </div>
         );
         })}
   </div>
   

   );
   };

When I try to execute, I am getting this below error
can anyone explain why it is happening

> 'toLowerCase')
