Error message when trying to load bundle through config file

[harshiy24]

We are using the following config.yaml file:

services:
  docker-registry:
    url: https://docker-snapshot.net
    type: oci
    credentials:
      bearer:
        scheme: "Basic"
        token: "username:password"
bundles:
  authz:
    service: docker-registry
    resource: docker-snapshot.net/testorg/policy-deployment-policy:1.0.0
    persist: true
    polling:
      min_delay_seconds: 60
      max_delay_seconds: 120
persistence_directory: /var/opa

When OPA is run using the following command:
opa run -s -c config.yaml
This is the output:

What does the error: "Failed to load bundle from disk: bundle read failed: archive read failed: EOF" mean in this scenario?
The bundle is downloaded from Artifactory, but what does the error mean?

I believe it's merely pointing out that it did not find a bundle on disk, which it will look for first given how you've provided the persist: true option in your configuration. Since it fails at that, it goes on to download the bundle from the remote instead, which seems fine to me.
