[Bug]: aws_transfer_server: 'As2Transport must be specified to enable AS2 protocol'

[jgohlke1]

Terraform Core Version

1.3.7

AWS Provider Version

4.53.0

Affected Resource(s)

• aws_transfer_server

Expected Behavior

When deploying a transfer server and specifying AS2 as a protocol, the provider should provide AWS with an As2Transports value of HTTP.

https://docs.aws.amazon.com/transfer/latest/userguide/API_CreateServer.html

Actual Behavior

The apply is failing with the following error:

│ Error: creating Transfer Server: InvalidRequestException: As2Transport must be specified to enable AS2 protocol
│
│   with aws_transfer_server.server,
│   on all.tf line 5, in resource "aws_transfer_server" "server":
│    5: resource "aws_transfer_server" "server" {

There seems to be a mismatch between Terraform and CloudFormation

https://docs.aws.amazon.com/transfer/latest/userguide/API_CreateServer.html#TransferFamily-CreateServer-request-ProtocolDetails

The ProtocolDetails configuration is missing from Terraform. As @jgohlke1 said AWS seems to want Terraform to set the equivalent of:-

ProtocolDetails:
As2Transports:
- HTTP

in order to be able to set AS2 as one of the protocols enabled.

In any case whether this is related or not Terraform is missing the ability to configure ProtocolDetails
