Terraform Error:Invalid Credential

[FabioPiluso]

Hello,

I'm trying to run my first Terraform:

terraform {
required_providers {
panos = {
source = "PaloAltoNetworks/panos"
version = " 1.11.1"
}
}
}
provider "panos" {
hostname = var.panos_hostname
username = var.panos_username
password = var.panos_password
}

variable "panos_hostname" {
type = string
default = "192.168.1.101"
}

variable "panos_username" {
type = string
default = "admin"
}

variable "panos_password" {
type = string
default = "mypassword"
}

data "panos_system_info" "ngfw_info" { }

output "the_info" {
value = data.panos_system_info.ngfw_info

Terraform init works, but when I lunch Terraform plan I get:

Error: Invalid Credential
│
│ with provider["registry.terraform.io/paloaltonetworks/panos"],
│ on get-system-info.tf line 9, in provider "panos":
│ 9: provider "panos" {

Terraform v1.7.4
on linux_amd64
+ provider registry.terraform.io/paloaltonetworks/panos v1.11.1

Can you help me please?

Thank you!
