OKTA iDp, Auth0 SP, Cant redirect back to application?

I tried following this guide:

But I get the following error after OKTA successfully authenticates and POSTS to
https:///login/callback?connection=<connection_name>

Error Message:
invalid_request: IdP-Initiated login is not enabled for connection “OKTA”.

I’m using the Auth0 React SDK to initiate the loginWithRedirect.

Hi @hkung77,
