python fido2 server with if statement

Question

I'm using the this example as inspiration for my project about Yubikey. At the end of authenticate.html, I want to add an if-statement. So if the authentication is successfull redirect to a specific page, and otherwise recirect back to the homepage. I've tried different places for the if-statement:

.then(function(response) {
  var stat = response.ok ? 'successful' : 'unsuccessful';
  alert('Authentication ' + stat + ' More details in server log...');
}, function(reason) {
  alert(reason);
}).then(
  function() {
    if(stat=='successful'){
      window.location.replace('https://google.com')
    }
    else {
      window.location = '/';
    }
});
}

and

.then(function(response) {
  var stat = response.ok ? 'successful' : 'unsuccessful';
  alert('Authentication ' + stat + ' More details in server log...');
  if(stat=='successful'){
      window.location.replace('https://google.com')
    }
    else {
      window.location = '/';
    }
}, function(reason) {
  alert(reason);
}).then(
  function() {
});
}

I've never seen Javascript before, but it seemed that I couldn't get around Yubikey and Python (I'm familiar with python) not using JS. None of the above has worked the intented ways.

Asuming you're using fetch then the correct (and simplest) way of handling this would be something like the following:

fetch('some-super-secret-endpoint')
.then(response => {
    if(response.ok)
        window.location = 'https://google.com'
    else 
        window.location = '/'
}).catch(e => {
    console.error(e)
})
