Hi. I am using nodejs with express for my rest api. I am using the auth config. Lets say the login fails, then the user gets redirected to localhost:3000/callback by default when using the auth config for express. However I want to override the post request for /callback, but still maintain most of the original functionality. I mainly just want to display the errors in a better way than a default error thrown from nodejs. For example the acces denied error, which happens when the user doesnt accept the tenant terms.

Hi @elias.knudsen

Welcome back to the Auth0 Community!

From the Auth0 perspective the detailed error message is passed in the returned callback request. Detailed parameters are showed here [Customize Error Pages](https://auth0.com/docs/customize/universal-login-pages/custom-error-pages#parameters)

on your side you will need to have a error handler that will check for errors from callback and render proper error message.

Thanks  
Dawid
