Auth0 is supposed to handle this route.
You need to put the domain of your Auth0 tenant in the auth_config.json file, not your application domain.
So it should be something like <yourtenant>.auth0.com (not uptimai-dashboard.netlify.com)
{
"domain": "<yourtenant>.auth0.com",
"clientId": "iS5oRqGaI4ZHiAiS1RwDjvYg3s9y0nWF"
}
