Internationalization not working in new universal login - Angular

Hi @vuscan.marius,

Thanks for reaching out to the Auth0 Community!

I understand you have issues passing in the ui_locales query parameter when using the loginWithRedirect method.

Just to clarify, could you confirm if you are calling the function similar to the following?

loginWithRedirect() {
  this.auth.loginWithRedirect({
    ui_locales: 'ro'
  });
}

Doing so should call the /authorize endpoint with the ui_locales query parameter appended. For example:

https://{yourDomain}/authorize?
    response_type=code&
    client_id={yourClientId}&
    redirect_uri={https://yourApp/callback}&
    scope={scope}&
    state={state}&
    ui_locales=ro

If you continue having issues, could you please capture these events in a HAR file and send them to me via DM?

I look forward to your reply.

Thanks,
Rueben
