Error: The terraform-provider-render_v1.2.0.exe plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Thanks for raising @matifali

What is your terraform configuration, are you able to share your terraform files?

[jackall3n]

I think, given where it's broken, it's failing to find a user which an email address you provided in the provider "render" block. Can you confirm if there's an existing user with that email address?

I've pushed up a new version with additional logging and error handling around this area to avoid the nil reference error

[matifali]

Yes sure. I am actually trying to write a terraform template for https://github.com/coder/coder.
I will post my terraform code later today.

[matifali]

Sorry for being late; I had been quite busy.
Here is my complete terraform code; I am getting the same error.

[tazarov]

@matifali, found a workaround of sorts:

variable "render_api_token" {
  sensitive   = true
}

variable "render_user_email" {
  sensitive   = true
}

provider "render" {
  api_key = var.render_api_token
}

data "render_owner" "render_owner" {
  email = var.render_user_email
}

resource "render_service" "my_service" {
  name = "my_service"
  repo = var.my_service_repo
  branch = var.my_service_branch
  owner = data.render_owner.render_owner.id
  ...
