I am trying to deploy the sample Guestbook Helm Application with ArgoCD, using a private repo with SSH. I am getting the below error.

Error

rpc error: code = Unknown desc = error creating SSH agent: "SSH agent requested but SSH_AUTH_SOCK not-specified"

I've tried both URL formats with:

git@github.com:myOrg/myrepo.git 

and

ssh://git@github.com/myOrg/myrepo.git

Neither work and both produce the same error. When I login to the GUI and configure the repo manually, copy and paste my private key that works, but when deploying with the YAML below, it doesn't

Application.yaml
