Overview of the Issue

While the failed information was reported when building an image using an HCL format configuration, the target image can be successfully built by a JSON format configuration with the same content.

Reproduction Steps

HCL format configuration(named alicloud.pkr.hcl):

packer init alicloud.pkr.hcl

packer build alicloud.pkr.hcl

Plugin and Packer version

Plugin version: alicloud v1.0.1

Pakcer version: packer v1.7.10

Simplified Packer Buildfile

`packer {
required_plugins{
alicloud = {
version = ">= 1.0.1"
source = "github.com/hashicorp/alicloud"
}
}
}
source "alicloud-ecs" "install-sgx"{
image_name = "sgx-env-installed"
source_image = "ubuntu_18_04_uefi_x64_20G_alibase_20210609.vhd"
ssh_username = "root"
instance_type = "ecs.g7t.large"
io_optimized = true
internet_charge_type = "PayByTraffic"
system_disk_mapping = {
"disk_category" = "cloud_essd"
}
run_tags = {
"Built by" = "Packer"
"Managed by" = "Packer"
}
}

build{
sources = ["sources.alicloud-ecs.install-sgx"]

This is a HCL format problem, you can use "system_disk_mapping" without "=" like this:
system_disk_mapping {
disk_category = "cloud_essd"
}
that's packer-plugin-alicloud define "system_disk_mapping" as a struct, and define "run_tags" as a Map,
so you can use "run_tags" with "=" like
run_tags = {
"Built by" = "Packer"
"Managed by" = "Packer"
}
