Error: creating custom disk: environment: line 1: pvesm: command not found

[testdcpractice]

Hello. I'm using bpg/proxmox 0.81.0. When running as a non-root user(I mean username = var.pm_user), I get an error when creating a virtual machine in Proxmox 8.3.3:
│ Error: creating custom disk: environment: line 1: pvesm: command not found.
However, if I use the telmate provider with the same non-root credentials, this error does not occur, and the virtual machine is created without any issues. If I use the root user with bpg/proxmox 0.81.0, the virtual machine is created without errors. What could be the issue? Does bpg/proxmox only work with the root user? On the Proxmox server, I added the username = var.pm_user to the root group

terraform {

    proxmox = {
      source  = "bpg/proxmox"

Hey @testdcpractice 👋🏼

For non-root user access you'd need to configure sudo permissions as explained here: https://registry.terraform.io/providers/bpg/proxmox/latest/docs#ssh-user

I solved the issue. The sudo utility wasn't installed on the Proxmox host. After I installed sudo and added the user (username = var.pm_user) to the sudo group, the virtual machine was created without any issues.
