Azure DevOps: Error importing repository when both source and destination repos are within same private ADO org

I want to import a repo called iac-example-app from Source Project into imported-repo in Destination Project within the same org we’ll call devopsorg, and am getting an error.

The plan works as expected:

# module.example.azuredevops_git_repository.imported_repo will be created
  + resource "azuredevops_git_repository" "imported_repo" {
      + default_branch = (known after apply)
      + id             = (known after apply)
      + is_fork        = (known after apply)
      + name           = "imported-repo"
      + project_id     = "<redacted>"
      + remote_url     = (known after apply)
      + size           = (known after apply)
      + ssh_url        = (known after apply)
      + url            = (known after apply)
      + web_url        = (known after apply)

      + initialization {
          + init_type   = "Import"
          + source_type = "git"
          + source_url  = "https://dev.azure.com/<redacted>>"
        }
    }

The error is when they apply occurs.

Here is my error:

2020-09-03T20:29:28.6888902Z Error: Error expanding repository resource data: Initialization strategy not implemented: Import

Here is my code:

provider "azuredevops" {
      alias                 = "devopsorg"
      version               = ">= 0.0.1"
      org_service_url       = "https://dev.azure.com/<redacted>/"
      personal_access_token = "<redacted>"
    }

# Get the data for the Source Project
data "azuredevops_project" "sourceproject" {
  provider     = azuredevops.devopsorg
  project_name = "Source Project"
}

# Get the data for the Source Repo
data "azuredevops_git_repositories" "iac-example-app" {
  provider   = azuredevops.devopsorg
  project_id = data.azuredevops_project.sourceproject.id
  name       = "iac-example-app"
}

# Get the data for the Destination Project
data "azuredevops_project" "destinationproject" {
  provider     = azuredevops.devopsorg
  project_name = "Destination Project"
}

resource "azuredevops_git_repository" "imported_repo" {
  provider   = azuredevops.devopsorg
  project_id = data.azuredevops_project.destinationproject.id
  name       = "imported-repo"

  initialization {
    init_type = "Import"
    source_type = "git"
    source_url  = data.azuredevops_git_repositories.iac-example-app.repositories[0].url
  }
}

The Azure DevOps personal access token being used has full access to everything in the org, and the user owning the PAT (myself) can import the repo manually.

Any ideas?

It appears I’m here to answer my own question - again.

The import function has yet to be released, despite the documentation and the results of the terraform plan leading me to believe it should be working.
