Going through Kratos Documentation and found this Using Ory Kratos it's possible to consume OAuth2 and OpenID Connect, and/or create an OAuth2 and OpenID Connect Provider by combining Ory Kratos with Ory Hydra . Is there any reference for how to create an Oauth2 & openid connect provider using a combination of Kratos and Hydra ?

Not sure if it helps but we managed to implement our own solution (in go) based on this sample : https://github.com/atreya2011/go-kratos-test.

Check out this excellent blogpost: https://blog.px.dev/open-source-auth/#integrated-kratoshydra-design As it mentions we are planning to make the integration much easier , tracked in this issue: https://github.com/ory/kratos/issues/273 Then we will also create some guides on how to do it from our side 💪 Also see the “Run your own OAuth2 server” post

@User I tried that, also I updated the dependency of hydra (v1.11.7) and kratos(0.9 using cloud) but post that start getting error as
