Error with access token in Auth0?

Question

User identification

Everything works correctly if I have a standard authorization page (authorization, registration, login with google and linkedin). But when I turn on 'Custom login page' authorization through google and linkedin starts to work incorrectly. In the database, Auth0 shows that the user is logged in, in the database too, but there is no idToken.
What do you think, how can I fix it?
