Overview of the Issue

The Scaleway Packer plugin fails to build an image. This error appears exclusively for block storage SSD images.

Reproduction Steps

1. Set all the required Scaleway environment variables as documented
2. Run Packer using:

packer build -var="scw_commercial_type=DEV1-S" -var "image_size_in_gb=50" -var "image_name=foo" foo.pkr.hcl

Plugin and Packer version

From packer version

packer v1.8.1

Plugin version:

v1.0.3

Simplified Packer Buildfile

packer {
  required_plugins {
    scaleway = {
      version = "1.0.3"
      source  = "github.com/hashicorp/scaleway"
    }
  }

  required_version = ">= 1.5.4"
}

# Scaleway image ID or label
variable "scw_image_id" {
  type    = string
  default = "ubuntu_focal"
}

# Scaleway VPS type
variable "scw_commercial_type" {
  type = string
}

# Image name is the resuling image name
variable "image_name" {
  type = string
}

# Volume size in GB, defaults to 0 for a standard local SSD configuration
variable "image_size_in_gb" {
  type    = number
  default = 0
}

source "scaleway" "foo-image" {
  image            = var.scw_image_id
  commercial_type  = var.scw_commercial_type
  image_size_in_gb = var.image_size_in_gb
  ssh_username     = "root"
  image_name       = var.image_name
}

build {
  sources = ["source.scaleway.foo-image"]
}

Maybe the timeout was a bit too short by default. Basically, the snapshot was not yet done that the image tried to exist. Could you try to relaunch it?

[karelorigin]

I have tried this various times, same problem @remyleone. Even if that were the case, it shouldn't be that unreliable

[karelorigin]

Were you able to reproduce it? @remyleone

Hello @karelorigin, regarding the error you encountered, I was able to reproduce it using the plugin version 1.0.3, this behavior is fixed in the last release (see the PR ad44180).

I suggest you to upgrade your version to 1.0.5. Feel free to comment and reopen the issue if needed.
