Guzzle 6.x / Not getting expected result - php

Question

I have a restful API. when I run POSTMAN on the following URL, I receive as response as follows:
POSTMAN RUN URL
DELETE
https://www.example.com/api/v1/Blog/blog/13
{
"status":"Failure",
"message":"The specified blog post could not be found"
}
The above is of course expected, however, I am unable to read in "status" and "message". How do I get that reply? Here is my present code:
$entry_id = $this->uri->segment(3);
$theUrl = $this->config->item('base_url').'api/v1/Blog/blog/'.$entry_id;
// tested $theUrl and works
$client = new GuzzleHttp\Client([
'base_uri' => $theUrl,
'timeout' => 3.0,
'http_errors' => FALSE
]);
$response = $client->delete($theUrl);
$code = $response->getStatusCode();
$response = $client->delete($theUrl);
$x = $response->getBody();
echo "<pre>";
echo var_dump($x); // cannot see message or status anywhere.
echo "</pre>";
Your suggestions much appreciated.

I have now tried this revised code but still cannot see the STATUS or MESSAGE date in the reply:
$entry_id = $this->uri->segment(3);
$theUrl = $this->config->item('base_url').'api/v1/Blog/blog/'.$entry_id;
$client = new GuzzleHttp\Client([
'timeout' => 3.0,
'http_errors' => FALSE
]);
$response = $client->delete($theUrl, ['debug' => true]);
$code = $response->getStatusCode();
$x = $response->getBody();
echo "<pre>";
echo var_dump($x);
echo "</pre>";
die();
Here is the dump and the debug info:

Answer 1

I think the base_uri parameter for new GuzzleHttp\Client is not needed. The base_uri parameter is used to set a base url. (http://docs.guzzlephp.org/en/latest/quickstart.html?highlight=base_uri) All calls to the client should then use relative uris. Since you are using an absolute url in the delete function call, you should not need the base_uri parameter.
Also you are calling the delete function twice: $response = $client->delete($theUrl).

Answer 2

In according to docs.
You should do
$x = $response->getBody()->getContents();
Or cast body to string:
$x = (string)$response->getBody()
