    display.innerHTML = "";
    let regex = new RegExp(textInput, 'ig');
  
    for(let i=0;i<country.length;i++){
      if(regex.test(`${country[i].countryRegion}`)){
        display.innerHTML += `
        <h3>${country[i].countryRegion}</h3>
        <div id="data-negara">
        <div id="konfirmasi">
        <h4>Konfirmasi</h4>
        <p>${country[i].confirmed}</p>
        </div>

        </div>

            break;
        }

In addition to Zai's answer, I think it would help you to remove this part of the code:

if( regex.test == false)

and leave a pure else branch, without any if in it.

Try using trycatch, that’s the easiest solution. The current code in your method cut it and add it to the try section and manage your error handing in the catch block.

Or add an if statement
