---------------------- Yes, you can cause an error to be raised during templating in Garden. If a template string resolves to an undefined value, an error is thrown by default. This can be used to prevent Garden from continuing if a certain condition is not met. For example, if you have an

if

statement in your configuration and one branch is not permitted, you can use a template string that will resolve to an undefined value in that branch. This will cause an error to be thrown and Garden will stop. Here is an example of how you can use a template string in your configuration:

yaml
kind: Project
providers:
  - name: kubernetes
    kubeconfig: ${var.kubeconfig}

In this example, if

var.kubeconfig

is not defined, Garden will throw an error and stop. However, please note that if you want to allow a template string to resolve to an undefined value without throwing an error, you can do so by adding a

?

after the template, like so:

yaml
kind: Project
providers:
  - name: kubernetes
    kubeconfig: ${var.kubeconfig}?

In this case, if

var.kubeconfig

is not defined, no error will be thrown and Garden will continue with the default value for the field in question. For more information, you can refer to the Garden documentation on variables and templating (). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
