No keys found in file

Hi,

I have .sops.yml config in my root repository like this:

---
creation_rules:
- arn: 'arn:aws:kms:ap-southeast-1:XXXX:key/xxxxx'
  role: 'arn:aws:iam::XXX:role/XXXX'

I ran this command:

 sops -e -i kube_config_cluster.yml

and this is the output of kube_config_cluster.yml

I ran sops -d -i kube_config_cluster.yml and show output like this:

No keys found in file

Somebody can help me on this ?

Start with the repository's handling of .sops.yml and the metadata in kube_config_cluster.yml. Reproduce encryption and decryption with the shown AWS KMS rule, then trace why the resulting sops.kms list is empty. Done means the reported configuration either decrypts successfully or the cause and required configuration are documented.
