Unknown argument on field of type “Mutation”

Question

I am working on laravel, magento and graphql. I am trying use mutation to grab a data and send to api. But

I am getting below errors -

          +"line": 2
          +"column": 156
        }
      ]
    }
  ]
}

Here is my graphql in magento -

type Mutation {

    pxFusionPostRequest(input: PxFusionRequestData): String @resolver(class: "Limesharp\\Windcave\\Model\\Resolver\\PxFusionPostRequest")
    
}

input PxFusionRequestData {
    card_num: String!
    nme_card: String!
    ex_mnth: String!
    ex_yr: String!
    cvc2: String!
    action: String!
    dps_px_pay: String!
    session_id: String!
}

And I calling it using laravel like -

public function pxFusionPostRequest($input){
        try {
            $response = $this->sendGraphQL('post', 'queries/payment/px-fusion-post-request.graphql', [
                'card_num'      =>  $input['cardNum'],
                'nme_card'      =>  $input['nmeCard'],
                'ex_mnth'       =>  $input['exMnth'],
                'ex_yr'         =>  $input['exYr'],
                'cvc2'          =>  $input['cvc2'],
                'action'        =>  $input['action'],
                'dps_px_pay'    =>  $input['dpsPxPay'],
                'session_id'    =>  $input['sessionId']
            ]);

            dd($response);
            
            if ($response->data->pxFusionPostRequest == null) {
                throw new GraphQlLogicException($response->errors[0]->message);
            }

            $data = $response->data->pxFusionPostRequest;
            return response()->json($data);
        } catch (\Exception $e) {
            return response()->json(['message' => $e->getMessage()])->setStatusCode(400);
        }
    }

And this px-fusion-post-request.graphql

mutation ($card_num: String!, $nme_card: String!, $ex_mnth: String!, $ex_yr: String!, $cvc2: String!, $action: String!, $dps_px_pay: String!, $session_id: String!) {
    pxFusionPostRequest(card_num: $card_num, nme_card: $nme_card, ex_mnth: $ex_mnth, ex_yr: $ex_yr, cvc2: $cvc2, action: $action, dps_px_pay: $dps_px_pay, session_id: $session_id)
}

Basically, I am passing user card details to magento and creating a post request. But, I am not sure why it is saying unknown argument as I am passing it.

Answer 1

Your mutation is expecting one argument with name input and type PxFusionRequestData , but you are trying to pass all the subfields as parameters. Try this:

mutation ($input: PxFusionRequestData) {
    pxFusionPostRequest(input: $input)
}
