I am trying to issue a certificate for my ingress and nothing seems to be working.

Error logs so far

$ kubectl describe ingress

Could not determine issuer for ingress due to bad annotations: failed to determine issuer name to be used for ingress resource

$ kubectl get certificate --all-namespaces

No resources found

$ kubectl logs cert-manager-XXXX

A breakdown of what I have done do so

1. I have used ClusertIssuer and Issuer alternatively in my issuer manifest (letsencrypt staging and prod). Not working
2. I have deleted and reinstalled cert-manager. Currently using v1.6.1. Not working
3. Removed kubernetes.io/tls-acme: "true". Not working
4. Changed to latest API cert-manager.io/v1. Not working
