No repository : The repository for this project does not exist

Let me set up my context of the issue here:

We are in process of migrating our standalone Gitlab application to the Kubernetes platform. The K8s platform we are using is Azure Kubernetes ( AKS). While we are designing our migration we have segregated GitLab components like Redis, Postgresql, and Gitlay server as external services.

We have successfully backed and restored the Postgresql server and migrated Repositories, snippets, and other storage using rsync service.

We have a standalone Gitaly server where we have backed our project repo. Gita running on K8s is pointed to the Standalone Gitaly server and the project repo on Gitaly is active. the backed projects from standalone GitLab have been properly copied into Gitaly server, but when we go on to Gitlab browser to access these projects we are getting the error 😞

No repository The repository for this project does not exist.

also from the admin view when we open a project, we see : repository: does not exist access: Private__
