serverless-prune-plugin not working

[yo-ga]

Hi,

We're currently using the serverless-prune-plugin to remove unused Lambda function versions, but we've encountered an issue where the plugin does not delete the previous unused versions of the warmup function as expected.

• Context

  • Plugin Version
    • serverless-plugin-warmup@8.2.1
    • serverless-prune-plugin@2.0.2
  • Serverless Framework Version: serverless@3.38.0

• Steps to Reproduce

1. Deploy the service multiple times, creating several versions of a Lambda function.
2. Configure serverless-prune-plugin to keep only the latest N versions (e.g., N = 5).
3. Deploy again and observe that older versions remain in AWS.

• Expected Behavior

1. Older versions beyond the specified N should be removed from AWS.

• Actual Behavior

1. The older versions remain in AWS even after the plugin is configured and the service is redeployed.

• Additional Information

1. Is there any specific configuration we might be missing to ensure these unused versions are pruned?

Hi @yo-ga ,

I don't use serverless-prune-plugin so I have no idea how that plugin works or why it doesn't work in this case.
