Describe the bug
Trying to use the remote_exec provisioner to execute commands post installation. When we use the examples provided in the documentation we get an error.

To Reproduce
Steps to reproduce the behavior:

1. define the following in any maint.tf

  connection {
    host     = self.resource_configuration[*].ip_address
    user     = var.upn_username
    password = var.domain_password
    type     = "ssh"
  }
 
  provisioner "remote-exec" {
    inline = [
      "echo hello"
    ]
  }

2. Terraform command
   terraform apply

3. Error
   Error: Incorrect attribute value type: Inappropriate value for attribute "host":
   string required.

Expected behavior
remote command to be executed on the target

Desktop (please complete the following information):

• OS: Windows 2016 and CentOS 7

Extra Information
If i remove the block above and just output the information the information is displayed as expected but in an array and not a single string

output "vm_name" {
  value = ["${vra7_deployment.deployment[*].resource_configuration[*].name}"]
}
 
output "vm_ip" {
  value = ["${vra7_deployment.deployment[*].resource_configuration[*].ip_address}"]
}

The issue appears to be related to the self object and the way the data is return from the data map from the provider!?

Update

I was able to do a remote_exec using this block

connection {
    host     = element(self.resource_configuration[*].ip_address, 0)
    user     = var.upn_username
    password = var.domain_password
    type     = "ssh"
  }
 
  provisioner "remote-exec" {
    inline = [
      "echo hello"
    ]
  }

Need to do more testing but so far so good

@Prativa20 is this the expected behavior? If so should we update the documentation to reflect this?

Yes @hobovirtual, we should update the documentation. Thanks for looking into it.
