Error when using azuredevops as provider in terraform init

[janethavideveloper]

In my main.tf file I have added azuredevops as the provider.

provider "azuredevops" {
  org_service_url       = var.devops_org_service_url
  personal_access_token = var.devops_personal_access_token
}

But when I try to terraform init there is an error as follows.
