Authentication fails with Invalid State and AnomalyDetected


#1

I have an old system using angular v1 and auth0-js v6.8.4. I haven’t updated the auth0 library for a long time and it’s all working fine. Until a couple of days ago, the login function started to throw 403 error:

code:"access_denied"
description:"Invalid state"
name:"AnomalyDetected"
statusCode:403

This is my sign in code:

auth.signin({
    connection: 'Username-Password-Authentication',
    username: $scope.user.email,
    password: $scope.user.password,
    authParams: {
        scope: 'openid name email' // Specify the scopes you want to retrieve
    }
},function(){},function(err){
  alertService.error(err['details']['description']);
},'Auth0');

Does any body know what has been changed recently to auth0? Since it’s a pretty old system, I just want to keep it working without updating the libraries in angular code. Many thanks.
