Laravel openssl_private_encrypt（）：密钥参数不是有效的私钥

Question

I am trying to connect to Chef API with Laravel using PHP-Chef . I have tried to set up my chef config with the data that I got from knife.rb in .chef folder. I have setup client and a key according to the instructions from Knife.rb . But I get:

openssl_private_encrypt(): key param is not a valid private key

And in my controller when I do dd($this->key) I get null in return. This is my controller:

protected $server;
protected $client;
protected $key;
protected $version;

public function ___construct()
{
  $this->server = config('chef.server');
  $this->client = config('chef.client');
  $this->key = config('chef.key');
  $this->version = config('chef.version');
}

/**
 * Get all dns records
 */
public function index()
{
  dd($this->key);
  $chef = new Chef($this->server, $this->client, $this->key, $this->version);

  // API request
  $response = $chef->get('/');
  dd($response);
}

And this is my config chef.php

return [
'server'    => 'https://172.16.0.227:443/organizations/myOrganizationsName',
'client'    => 'chef-validator',
'key'       => '/Users/myName/.chef/ORGANIZATION-validator.pem',
'version'   => '12.7.0',
"enterprise" => false
];

因为我想这是对的，所以只是将其复制下来以作答，但这听起来像是错误的密钥路径或文件权限，以致PHP无法读取密钥数据。
