[Koha] Redirect / Callback URI

We're setting up Okta as an authentication provider using OIDC but we're stumped at the moment. We're seeing the following error: *Your request resulted in an error. The 'redirect_uri' parameter must be a Login redirect URI in the client app settings:* We're seeing the partial path but it appears to want the full URL string here. Does anyone have any examples they are willing to share with us? Thank You, Scott Scott Marriott, Emerson
