Debug Output

Crash Output

Expected Behavior

Public key should be aprovisioned correctly, since it follows the convention requested on the documentation:
"public_key - (Required) The Public Key which should be used for authentication, which needs to be at least 2048-bit and in ssh-rsa format. Changing this forces a new resource to be created."

Actual Behavior

When terraform plan is run, the following error appears:
terraform plan
2020/03/08 15:19:27 [WARN] Log levels other than TRACE are currently unreliable, and are supported only for backward compatibility.
Use TF_LOG=TRACE to see Terraform's internal logs.

2020/03/08 15:19:28 [ERROR] : eval: *terraform.EvalSequence, err: Error decoding "admin_ssh_key.0.public_key" for public key data

Error: Error decoding "admin_ssh_key.0.public_key" for public key data

on vm.tf line 86, in resource "azurerm_linux_virtual_machine" "vm1":
86: resource "azurerm_linux_virtual_machine" "vm1" {

Steps to Reproduce

Additional Context

It didn't work either with format ---- BEGIN SSH2 PUBLIC KEY ---- (old resource type azurerm_virtual_machine used to work with this format)
