If the file is empty, e.target.result.split(',')[1] === undefined, resulting in an invalid encoding error when method atob is triggered. Set a catch clause to catch empty files. and give it a default empty string.

Complete error:
DOMException: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded. {message: "Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.", name: "InvalidCharacterError", code: 5
