I got a Service not found: http://localhost:8080 error when trying to login using lock:

Related code:
const lock = new Auth0Lock(
'rl8Kjiy21AZOd62jNXGuNgIU********',
'*******.auth0.com',
{
allowedConnections: ['Username-Password-Authentication'],
rememberLastLogin: true,
languageDictionary: { title: 'FindEarth' },
language: 'en',
closable: false,
theme: {
primaryColor:'#3A99D8',
logo: 'https://avatars2.githubusercontent.com/u/19509447?v=3&s=200'
},
auth: {
redirect : false,
responseType: 'token',
sso: true
}
}
);
lock.on('authenticated', (err, authResult) => {
console.log('err', err);
console.log('authenticated', authResult);
});
lock.on('authorization_error', (error) => {
console.log('authorization_error', error);
});
lock.show(); // to display the lock view
Note that the console.log's are from the authenticated event, Im not sure if that is ok or the error should come from authorization_error event.
I followed the tutorials and even downloaded the sample project and I got the same error, I already add my localhost url to Allowed Callback URLs. I assume Im missing something in the configuration.
Im using Google Chrome Version 55.0.2883.95 (64-bit), in a macOS Sierra. The lock version that im using is 10.10.2.
Do you have any active rule in your account or maybe a custom db?
Yes I have a rule configured, but I disabled it and the error keep happening. No I don't have a custom db.
More Info:
When I click the try all rules with button, and select Username-Password-Authentication (the one Im using) it redirects me to this page, even If I disable my rule:

Can you share your account name?
keepers-co
seems that you set that as your default audience but you dont have an API with that identifier

Clear that setting and it should work fine
It worked! thank you very much @glena!
@glena where's the "Default Audience" section located?
go to https://manage.auth0.com, click on the right top corner and it will unfold a menu.
Click on settings, and you should see it in the second section of the first tab
