Install AWS cloudhsm_client .deb file

I am trying to bundle up the AWS CloudHSM client into a snap and getting this error:

Downloading 'cloudhsm-client_latest_amd64.deb'[===...=====] 100%
Building cloudhsm 
Failed to copy '/root/parts/cloudhsm/build/etc/cloudhsm': it's a symlink pointing outside the snap.
Fix it to be valid when snapped and try again.

Here is my YAML

name: cloudhsm-azemon
base: core
version: '0.1.0'
summary: AWS CloudHSM Client
description: |
  This is the AWS CloudHSM client.
  See https://docs.aws.amazon.com/cloudhsm/latest/userguide/install-and-configure-client-linux.html

grade: devel 
confinement: devmode 

parts:
  cloudhsm:
    plugin: dump
    source: https://s3.amazonaws.com/cloudhsmv2-software/CloudHsmClient/Xenial/cloudhsm-client_latest_amd64.deb
    source-type: deb
    stage-packages:
      - libjson-c2

To me, this looks like AWS created a broken .deb file. Is there any way to work around it?
