stage_domain_name output for websocket api returns wss protocol and stage_id

[acormier-maia]

Description

When creating a websocket API, the output stage_domain_name contains the wss:// protocol and the stage_id prefix. This is due to the regex in the output value not matching the wss protocol.

⚠️ Note

Before you submit an issue, please perform the following first:

1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
2. Re-initialize the project root to pull down modules: terraform init
3. Re-attempt your terraform plan or apply and check if the issue still persists

  route_selection_expression = "$request.body.action"

  create_domain_name = false

  stage_name = "ws-router"

  stage_default_route_settings = {
    logging_level            = "INFO"
  }

  routes = {
    "$connect" = {
      operation_name = "ConnectRoute"

      integration = {
        uri = var.websocket_connect_fn_arn

output "stage_domain_name" {

Should only be the domain name.

what is the use case for this?

[acormier-maia]

I need to pass the domain name into Cloudfront. This way we have a single domain name which proxies S3, API Gateway. I am putting up a PR now.
