Argument 1 passed to __construct() must be an instance of GuzzleHttp\Client - php

Question

I'm trying to "use" a vendor script to connect to feefo api (an online reviews service) but when I try and use the script it gives me this error:
Type error: Argument 1 passed to
BlueBayTravel\Feefo\Feefo::__construct() must be an instance of
GuzzleHttp\Client, null given, called in/Users/webuser1/Projects/_websites/domain.co.uk/plugins/gavinfoster/feefo/components/Feedback.php on line 47
Here is the vendor code I'm using:

And here is the code I'm using to try and use the fetch() method from the vendor class:
use Cms\Classes\ComponentBase;
use ArrayAccess;
use Countable;
use Exception;
use GuzzleHttp\Client;
use Illuminate\Contracts\Config\Repository;
use Illuminate\Contracts\Support\Arrayable;
use SimpleXMLElement;
use BlueBayTravel\Feefo\Feefo;
class Feedback extends ComponentBase
{
public $client;
public $config;
/**
* Container used for display
* #var BlueBayTravel\Feefo
*/
public $feedback;
public function componentDetails()
{
return [
'name' => 'Feedback Component',
'description' => 'Adds Feefo feedback to the website'
];
}
public function defineProperties()
{
return [];
}
public function onRun()
{
$this->feedback = $this->page['feedback'] = $this->loadFeedback($this->client, $this->config);
}
public function loadFeedback($client, $config)
{
$feefo = new Feefo($client, $config);
$feedback = $feefo->fetch();
return $feedback;
}
}
Won't allow me to call the Fetch() method statically so trying to instantiate and then use:
public function loadFeedback($client, $config)
{
$feefo = new Feefo($client, $config);
$feedback = $feefo->fetch();
return $feedback;
}
I've also tried type hinting the args like this:
public function loadFeedback(Client $client, Repository $config)
{
$feefo = new Feefo($client, $config);
$feedback = $feefo->fetch();
return $feedback;
}
But still I get the exception error above. I'm struggling to understand how to get past this. Any help for a newbie much appreciated :)

Answer 1

Just type hinting the function won't cast it to that object type. You need to properly pass the Guzzle\Client object to your function call.
// Make sure you 'use' the GuzzleClient on top of the class
// or use the Fully Qualified Class Name of the Client
$client = new Client();
$feedback = new Feedback();
// Now we passed the Client object to the function of the feedback class
// which will lead to the constructor of the Feefo class which is
// where your error is coming from.
$loadedFeedback = $feedback->loadFeedback($client);
Don't forget to do the same for the Repository $config from Laravel/Lumen
