Terraform Error - Error: update server is not set

Im creating a cname record set, but when i put the command "terraform apply", i got this message "Error: update server is not set". Im using Terraform v0.14.7.
In the azure platform in “DNS Zones” i have already created a zone called: tech.com.br

Anyone could help me ? What should i do ?

provider “azurerm” {
features {}

resource “dns_cname_record” “foo” {
zone = “tech.com.br.”
name = “foo”
cname = “info.tech.com.br.”
ttl = 3600

Hi @lucas.menck ,
if you shared all of your code then the code-base might lack proper definition of the dns provider.
