Retrieve salesforce error messages

[Crmmetry-Waba]

I have a lead creation method in my controller.

However the submission is failing since Ive add addtional fields to it. How do I get it to display the correct error message so I can address it quickly.

"Salesforce response error" as the error message just doesnt cut it, Id like to know if i have the wrong data type and where.

If you recommend guzzle could you please give an example

This is something I've utilized to get the error to display in a nice format, it utilizes the guzzle exception code.

try{
....
}
catch(\GuzzleHttp\Exception\RequestException $e){
            $error = array(
                "error_details" => "Error Exception Data => [" . $e->getResponse()->getBody() . "]",
                "error_code" => "SALESFORCE_EXCEPTION"
            );
            return json_decode(json_encode($error));
}
