Terraform list as input variable in Azure DevOps - azure-devops

Question

I am trying to pass list as variable to Azure DevOps release pipeline.
My variable declaration:
variable "allowed_audiences" {
description = "Allowed audiences"
type = list(string)
default = ["xyz", "abc"]
}
Then, in azure devops i am trying to pass value that i am storing in variable group:
["\"test\""]
In task, i am passing that variable like that:
-var="allowed_audiences=$(allowed_audience)" -var="environment=$(Release.EnvironmentName)"
But it still failes whatever i tried.

My question is, how to pass list of string as variable during Azure Devops release pipeline?
EDIT:
When i try this form:
-var='allowed_audiences=["\"$(allowed_audience)\""]' -var="environment=$(Release.EnvironmentName)"
I get this error:

Answer 1

I managed to do that. YOu need to delete quotes from var area and everything should be fine
-var=allowed_audiences=["\"$(allowed_audience)\""] -var="environment=$(Release.EnvironmentName)"
