i have followed the instructions on this page: Adding the 'group' Claim to the Okta ID Token to Match the Default 'Okta Basic' Template - Okta Workforce Connection - Auth0 Community
but for some reason i still see: Error transforming template due to missing keys (1) from IdP context
Any advice?
Sounds like the error is coming from the Auth0 side. Have you manually requested a token from your application in Okta (using the same authorization server as configured in Auth0) to confirm if the groups claim is present in the token?
