Issues with terraform apply

[rollovd]

Hello!
I try to launch terraform apply after terraform init (I'm following this guide: https://outerbounds.com/engineering/deployment/aws-k8s/deployment/#initialize-your-terraform-workspace). I'm using latest version of this repo.

But terraform apply initially returned me the following error:

╷
│ Warning: Argument is deprecated
│ 
│   with module.metaflow-datastore.aws_s3_bucket.this,
│   on .terraform/modules/metaflow-datastore/modules/datastore/s3.tf line 3, in resource "aws_s3_bucket" "this":

│

╵

│ 
│ An argument named "name" is not expected here.

I manually commented this argument, but afterwards I still have a lot of errors:

Could you help me to resolve it? Or maybe explain how to get rid of these issues?
Thank you in advance!
