Terraform crashes while attaching an existing Teamcity template

[shagun05]

Hey!

Terraform version: 0.13.5
TeamCity Enterprise 2020.1 (build 78475)

I am trying to use the teamcity_build_config resource with a pre-existing (Manually Created) Teamcity template as we are trying to port builds slowly over to terraform.
Teamcity side works fine and I get a new build associated with the template as expected. However, terraform crashes out while applying and taints the resource.

resource "teamcity_build_config" "solution_validation" {
  name        = "Solution Validation"
  project_id  =  "${teamcity_project.Cyara_Agent.id}"
  templates = ["GitSolutionValidationNetframeworkMonorepo"]
}

Error output through terraform:

teamcity_build_config.build: Creating...

Error: rpc error: code = Unavailable desc = transport is closing



Error: rpc error: code = Unavailable desc = transport is closing
