All of Chapter 2 works fine until this last bit.

Hi @SoldierCoder could you share your whole main.tf and .auto.tfvars files? It looks like your having an issue when trying to access a specific “github_issue_label.issues_labels” resource. Rather than having many “issue_labels” in your state it seems that you only have one.

Thanks @SoldierCoder!
It looks like you’ve got a typo in the first issue in your issues list in .auto.tfvars:
{
title = “Implement the Dockerfile’s builder stage”
body = <<EOT
The builder stage packages all the tools and compile-time dependencies for your
application. It has to build the mix release that will be copied in the running
stage.
EOT
labels = [“kind-infrastrcture”, “dockerfile”]
milestone = “infrastructure”
}
Rather than “kind-infrastrcture” it should say “kind-infrastructure”.
Let me know if that fixes the problem. Thanks!
