This seems similar to this issue.
The error message: Error: template: parseable/templates/logstream-job.yaml:51:37: executing "parseable/templates/logstream-job.yaml" at <$secret.keys>: can't evaluate field keys in type interface {}
The YAML:
logstream:
- name: "vector"
retention:
action: "delete"
duration: "30d"
Alas, I am not knowledgeable enough to debug it further.
