Uncaught exception for retryVoice = true

[amitbravo]

if I use retryVoice = true , it does not work , fail with "Uncaught exception" however working perfectly with false

sendOtp.retry(phone, false, function (error, data, res) {
if(data.type == 'success'){
console.log('resent successfully');
admin.database().ref('/users/' + phone)
.update({ code: code, codeValid: true }, () => {
response.send({ success: true });
});
}
else {
return response.status(422).send(err);
}
});
