Error : LAErrorAuthenticationFailed Authentication could not start because Touch ID has no enrolled fingers.

I followed the docs to implement the Touch ID but I have this error now

here is my code

 const clickHandler = () => {
TouchID.isSupported()
  .then(() => {
    console.log('yes'); // it console yes
    authenticate();
  })
  .catch(error => {
    Alert.alert('TouchID not supported');
  });
};

const authenticate = () => {
return TouchID.authenticate()
  .then(success => {
    Alert.alert('Authenticated Successfully');
  })
  .catch(error => {
    console.log(error); // it console Authentication could not start because Touch ID has no enrolled fingers.]
    Alert.alert(error.message);
  });

basically TouchID.isSupported() is Working but the TouchID.authenticate() 's not working

any clue what's the issue? or maybe solution
