sendOfferToInterestedBuyers Response is not JSON data error

[compadvance]

Hi mate , working on it recently , whatever I try this requests wont be successful , Response is not JSON data most commonly
whenever I use $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$offerRequest,$contentType); or $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$jsonString,$contentType); where $jsonString = json_encode($offerRequest);
What I missing , generated json file match ebay requirements perfectly and all required fields are there . Any hint would be much appreciated. Emil

public function send_Ebay_Offers($params){

$contentType = 'Content-type:application/json';
    //$offer_duration = ['unit'=>DAY,'value'=>2];
    //$offered_price  = ['currency'=>'GBP','value'=>$params['offerPrice']];
    $offered_price = ['value' => $params['offerPrice']];

    foreach ($params['listing_IDs'] as $listingID) {
        $offeredItems = [['listingID' => $listingID, 'price' => ['value' => $params['offerPrice']], 'quantity' => 1]];

        $offerRequest = new \macropage\SDKs\ebay\rest\negotiation\Model\CreateOffersRequest();
        $offerRequest->setAllowCounterOffer($params['allowCounterOffer']);
        $offerRequest->setMessage($params['message']);
        $offerRequest->setOfferedItems($offeredItems);

       // var_dump($offerRequest);die();
        //$jsonString = json_encode($offerRequest);
        $apiInstance = $this->apiInstance;
        
        try {
            $res = $apiInstance->sendOfferToInterestedBuyers($this->ebayId,$offerRequest,$contentType);
            print_r($res);
        } catch (\macropage\SDKs\ebay\rest\negotiation\ApiException $e) {
            // Capture and decode the error response
            $errorResponse = $e->getResponseBody(); // Get the raw response body
            $errorDetails = json_decode($errorResponse, true); // Decode JSON response to an associative array
            echo "EMIL Error: " . $errorDetails['errors'][0]['message'] ?? 'Unknown error';
        } catch (\Exception $e) {
            // Handle other exceptions (if any)
            echo "EMIL Exception: " . $e->getMessage();
        }
    }
}

hi there,
without knowing how the ebay response looks like it´s nearly impossible to help you.
first make sure you are using a correct oauth token that has the correct scopes and is valid.

here´s how I am doing that call, maybe it helps:

use GuzzleHttp\Client;

public function __construct(string $ebay_account_name)
    {
        $this->apiConfig   = $this->getEbayToken($ebay_account_name);
        $this->apiInstance = new OfferApi(
            new Client(),
            Configuration::getDefaultConfiguration()->setAccessToken($this->apiConfig->token)
        );
    }

public function sendOfferToInterestedBuyers(int $itemid): apiError|SendOfferToInterestedBuyersCollectionResponse
    {
        $offeredItem = new OfferedItem();
        $offeredItem->setListingId($itemid);
        $offeredItem->setQuantity(1);
        $offeredItem->setDiscountPercentage(config('discount.percent'));
        $offeredItems[] = $offeredItem;

        $createdOfferRequests = new CreateOffersRequest();
        $createdOfferRequests->setMessage(sprintf(config('discount.text'), config('discount.percent'), config('discount.duration.value')));
        $createdOfferRequests->setAllowCounterOffer(false);
        $createdOfferRequests->setOfferDuration(
            new TimeDuration(
                [
                    'unit'  => config('discount.duration.unit'),
                    'value' => (string)config('discount.duration.value')
                ]
            )
        );
        $createdOfferRequests->setOfferedItems($offeredItems);

        try {
            return $this->apiInstance->sendOfferToInterestedBuyers($this->apiConfig->marketplace, $createdOfferRequests);
        } catch (ApiException $e) {
            Log::error($e->getResponseBody());
            return $this->parseErrors($e->getResponseBody());
        }
    }

maybe it helps.
