This is my code

public function getPurchaseData(Request $request)
{
$credentialsPath = config(‘services.fcm.credentials_path’);

    if (!file_exists($credentialsPath)) {
        return response()->json(['error' => 'Credentials file not found'], 404);
    }
    // dd($credentialsPath);

    $fileContent = file_get_contents($credentialsPath);
    $decodedCredentials = json_decode($fileContent, true);

    $client = new Client();
    
    $client->setApplicationName('AI Dating');
    // dd($client);
    $client->setAuthconfig($credentialsPath);
    // dd($client);
    $client->addScope(AndroidPublisher::ANDROIDPUBLISHER); 
    $service = new AndroidPublisher($client);
    // dd($service);
    $packageName = config('services.google_play.package_name');
    $subscriptionId = config('services.google_play.subscription_id');
    $purchaseToken = config('services.google_play.purchase_token'); // Get purchase token from request
   
    // try {
        $result = $service->purchases_subscriptions->get($packageName,$subscriptionId,$purchaseToken);
        // dd('sdfdfdf',$result);
        $expiryTimeMillis = $result->getExpiryTimeMillis();
        $expiryDate = DateTime::createFromFormat('U', $expiryTimeMillis / 1000);
    
        $currentDate = new DateTime();
        $interval = $currentDate->diff($expiryDate);
        $daysRemaining = $interval->format('%a');
      return $daysRemaining;
        // echo "Days remaining: " . $daysRemaining;
    // } catch (Exception $e) {
    //     echo 'Error: ' . $e->getMessage();
    // }
}

I got error message

{ “error”: { “code”: 400, “message”: “Invalid Value”, “errors”: [ { “message”: “Invalid Value”, “domain”: “global”, “reason”: “invalid” } ] } }

I want to get details of that user subscription like
expire time
remaining days
payment amount
and plan details
