Packer build hangs on last command

My packer build seems to run all commands successfully, but keeps hanging on the last cmd. This is the end of my packer output on debug mode. I am unsure how to get past this. It seems to get stuck on removing the temporary script.

I am using the following provisioner:

  {
    "type": "shell",
    "script": "bootstrap/bootstrap.sh",
    "execute_command": "echo 'packer' | sudo -S env {{ .Vars }} {{ .Path }}"
  }

And the final error is:
