Spaces Lifecycle is not expiring files

I am trying to setup a lifecycle rule to delete all files older than 5 days. I can successfully PUT the lifecycle and confirmed it is up there with a GET. However, it doesn’t look like any files are getting removed.

Below is the rules.json file:

{ “Rules”: [ { “ID”: “Remove old files”, “Status”: “Enabled”, “Prefix”: “”, “Expiration”: { “Days”: 5 } } ] }

And here is the AWS command I used:

aws s3api --endpoint-url=https://nyc3.digitaloceanspaces.com
put-bucket-lifecycle-configuration
–bucket REDACTED
–lifecycle-configuration
file://rules.json

Am I missing something obvious?
