Thank you for posting your inquiry on the Auth0 Community!
Regarding logging out the current session after a 401 error, you can review this community post regarding the same matter. Even if the post addresses a NodeJS SDK implementation, it should be useful for your use case.
Alternatively, you can try adding the following code in the callback handler:
res.redirect(
`${AUTH0_ISSUER_BASE_URL}/v2/logout?${new URLSearchParams({
client_id: AUTH0_CLIENT_ID as string,
returnTo: BASE_URL,
})}`
)
.end();
You can also try to catch the 401 error and redirect the user to your /logout endpoint as follows:
window.location.href = “/api/auth/logout”;
Otherwise, whenever you receive a 401 Unauthorized error, there should not be any user information saved on Auth0 since they did not complete the login process, however you can make a call to you management api in order to delete the user if needed.
Please let me know if you have any other questions by leaving a reply on the post!
Kind Regards,
Nik
