Follow the example but get error when I run example for Terraform with Ansible

as i follow the example at https://www.digitalocean.com/community/tutorials/how-to-use-ansible-with-terraform-for-configuration-management

When I ran it terraform apply -var “do_token=${DO_PAT}” -var “pvt_key=/home/ubuntu/terraform-ansible/aws_rsa” -var “pub_key=~/.ssh/aws_rsa.pub”

I get an error

╷ │ Error: no ssh key found with name terraform │ │ with data.digitalocean_ssh_key.terraform, │ on provider.tf line 18, in data “digitalocean_ssh_key” “terraform”: │ 18: data “digitalocean_ssh_key” “terraform” { │ ╵

Not sure what I did wrong
