Laravel 7 giving 500 error when accessing external api when the response returned with status of 104 (but working for for status 200)

My question is I am accessing some external rest api like getServices if the get services response is like this

{
    "status": 200,
    "data": [
        {
            "country": "india",
            "qualfication": "B.tech",
            "educationId": 13,
            "city": "Mathurafgddsfwf",
            "endDate": null,
            "clgUniversity": "amar Nath",
            "startDate": "2010-05-22"
        }
    ]
}

everything is working fine for the above response from the external Api

but when the response is like this from external Api it is giving 500 error in browser

{
    "status": 104,
    "message": " not exist",
    "data": []
}

my controller code is

  public function getEducation(Request $request){
    //   dd($request);
        
        $cookie = \Cookie::get('datastore');
        $dataJson=json_decode($cookie,true);
        $username=$dataJson['data']['username'];
        $token= $dataJson['data']['token'];
        $phoneSecurity= $dataJson['data']['phone'];
        $userId=$dataJson['data']['userId'];
  
    
       

        $client =new Client();
        $data=array(  "username"=>$username,
        );
      
  
        $dataJson=json_encode($data);

        $headers['Content-Type']="application/json";
        $headers['X-Access-Token']=$token;
    
        $response=$client->request('POST',
        'http://localhost:8084/api/users/getUserEducationDetails'
        ,array("headers"=>$headers,"body"=>$dataJson));

        $body=$response->getBody()->getContents();
        $resText=json_decode($body,true);


      if(  $resText['status']==200)
        return response()->json($resText);
        if($resText['status']==104)
        {
            $newData=array("status"=>"104");
            $newData=json_encode($newData);
            $resText=$newData;
        }
      
        return response()->json($resText);
    }

In short when the external api returning response like this { "status": 104, "message": " not exist", "data": [] } laravel gives 500 internal server error

And the error showed inside the network tab inside response is

GuzzleHttp\Exception\ClientException: Client error: `POST http://localhost:8084/api/enimm/users/getUserEducationDetails` resulted in a `404 Not Found` response:
{"status":104,"message":" not exist","data":[]}
