I am trying to get data from airtable table named leads using phone number which i have got from another table. Here is the error I am getting

Airtable Error { error:'INVALID FILTER BY FORMULA',

message:'The formula for filtering records is invalid : Invalid Formula. Please check your formula text'

statusCode:422 }

my field type from which I am trying to get data is a phonenumber field and here is my code.

function CollectRecordsFromLeads(recordID,phoneNumber){
    console.log(phoneNumber);
   
    base("Leads").select({
        filterByFormula: `OR( New Number (Whatsapp)='${phoneNumber}')`, //New Number is the field name
        
    }).eachPage(function page(records, fetchNextPage) {   
       
        records.forEach(function(record) {
           
         
        });
        fetchNextPage();
    }, function done(err) {
        if (err) {
         console.error(err);
          return;
        }
       console.log(LeadRecordSet);

     });

I am new to Airtable api so any help could be great.
