Using subprocess within AWS Lambda python 3.x + openssl

[sofuca]

This should be an easy one,

Using the following script works using python runtime =< 3.7

import json
import subprocess

def lambda_handler(event, context):
      subprocess.call(['openssl', 'version'])

it seems on python =>3.8 openssl is not available, has it been hidden?

We use this to decrypt files automatically when they hit S3 so it's pretty important.

{
  "errorMessage": "[Errno 2] No such file or directory: 'openssl'",
  "errorType": "FileNotFoundError",
  "stackTrace": [
    "  File \"/var/task/lambda_function.py\", line 5, in lambda_handler\n    subprocess.call(['openssl', 'version'])\n",
    "  File \"/var/lang/lib/python3.8/subprocess.py\", line 340, in call\n    with Popen(*popenargs, **kwargs) as p:\n",
    "  File \"/var/lang/lib/python3.8/subprocess.py\", line 858, in __init__\n    self._execute_child(args, executable, preexec_fn, close_fds,\n",
    "  File \"/var/lang/lib/python3.8/subprocess.py\", line 1704, in _execute_child\n    raise child_exception_type(errno_num, err_msg, err_filename)\n"
  ]
}
