Git SSH private repository clone is not working for new workspaces

[kspradheep]

Bug description 🐞

We have 10+ workspaces and all uses SSH based VCS git clone. They're working with no issues. However, the private repository git clone is not working for newly created workspaces hence terraform plan shows "No changes. Your infrastructure matches the configuration."

Steps to reproduce

1. Create a workspace using VCS private repo with SSH as mentioned https://docs.terrakube.io/user-guide/vcs-providers/ssh
2. Run plan job

Expected behavior

The plan should show changes of terraform resources

Example repository

No response

Anything else?

No response

Maybe you can check your SSH key because for me it is working

I have this workspace that is using ssh connectivity as you can see here

I can see the plan correctly

[kspradheep]

Delete and recreate the workspace seems fixed the issue for me. I suspect SSH key was not selected/picked during workspace creation. Can we make "SSH Key" parameter as required field or automatically choose default Org level ssh key?

[alfespa17]

That wont be possible because not all the workspaces are private, terrakube also support public workspaces so the SSH Key should be optional
