set numbers as true but sometimes get random string no any number

[rhythm1993]

function getRandomString(length, options) {
const params = {
numbers: get(options, 'numbers', true),
letters: get(options, 'letters', true),
specials: get(options, 'specials', true),
};
return stringRandom(length, params);
}
......
Can see the function detail as above, I have only set the options as non-mandatory params, if no options passed here, all options will be true, but what I got the string have no at least one number...not always like this, but sometimes can not works.
