Getting the error: `serverless.variables.populateObject`

[Morraycage]

Hi hope you are doing well i'm using serverless 3.25.1

And my config is this:

  s3: !Ref ServerlessDeploymentBucket
  remover:
    buckets:
      - ${self:custom.s3.Ref}

I installed the package as it is in the Documentation but actually i'm getting this error ..

TypeError: this.serverless.variables.populateObject is not a function

Is the plugin is dead ? Because i'm not understanding do i have to set populateObject or something ? Because it's not in the documentation.

Thank you by advance

Is this plugin is an open source one ?

Cause i cannot create a pull request to fix the issue ..
