Post-processor failed: AuthFailure: AWS was not able to validate the provided access credentials

[choonming]

I've been trying to get the plugin to work on with my packer template. I'm using the Amazon EBS provider for my build and it works successfully with the assume role. However, when it comes to the post-provisioner stage, I get the following error saying invalid credentials when it is working on the builder.

source "amazon-ebs" "amazon-linux" {
  ami_name            = "${var.ami_prefix}-${var.type}-{{ timestamp }}"
  ami_regions         = var.ami_regions
  instance_type       = var.instance_type
  region              = var.primary_region
  source_ami          = data.amazon-ami.amazon-linux.id
  ebs_optimized       = true

  vpc_filter {
    filters = {

      "isDefault" : "false",
    }
  }

    filters = {
      "tag:Name" = "packer-imagebuilder-private-${var.primary_region}a"
    }
    most_free = true
    random    = true
  }

  assume_role {
    role_arn     = var.deployment_role_arn
    session_name = "packer-imagebuilder"
  }
}

build {

This error seems to occur when using an old STS token.
https://aws.amazon.com/premiumsupport/knowledge-center/iam-validate-access-credentials

The last release was over a year ago, so it's possible that only tokens issued by the post processor are still version 1.
