'How to fix request is missing required input tag

I am trying to get some products from a user's ebay account, but when I run my code I am only getting a that error "Your application encountered an error. This request is missing required input tag " or "." 

<?php

function print_d($array){    echo "<pre>\n";    print_r($array);    echo "</pre>\n";}

$mytoken = "************mytoken************";
$devId   = "************mydevId************";
$appId   = "************myappId************";
$certId  = "************mycertId************";

$wsdl_url = 'http://developer.ebay.com/webservices/latest/ebaySvc.wsdl';

$apiCall = "GetSellerList";

$credentials = array('AppId' => $appId, 'DevID' => $devId, 'AuthCert' => $certId);

$client = new SOAPClient($wsdl_url, array('trace' => 1, 'exceptions' => 0, 'location' => "https://api.ebay.com/wsapi?callname=$apiCall&appid=$appId&siteid=0&version=803&Routing=new"));

$eBayAuth = array('eBayAuthToken' => new SoapVar($mytoken, XSD_STRING, NULL, NULL, NULL, 'urn:ebay:apis:eBLBaseComponents'),
                    'Credentials' => new SoapVar ($credentials, SOAP_ENC_OBJECT, NULL, NULL, NULL, 'urn:ebay:apis:eBLBaseComponents'));  

$header_body = new SoapVar($eBayAuth, SOAP_ENC_OBJECT);    

$header = array(new SOAPHeader('urn:ebay:apis:eBLBaseComponents', 'RequesterCredentials', $header_body));                

//set the API call parameters

$params = array('UserID'=>'**sellerid**','DetailLevel'=>'ReturnAll','WarningLevel'=>'High','IncludeWatchCount'=>'true','Pagination'=>array('EntriesPerPage'=>'20','PageNumber'=>'1'),'Version' => '803', 'CreateTimeFrom'=>'2019-07-01T01:01:02.768Z', 'CreateTimeTo'=>'2019-08-22T01:01:02.768Z');  

$request = $client->__soapCall($apiCall, array($params), NULL, $header);  //make the actual API call

print_d($request);

?>

this is what i get :

    [Timestamp] => 2019-08-23T05:54:30.954Z

I've got the same error Your application encountered an error. This request is missing required input tag "" or In der Anwendung ist ein Fehler aufgetreten. In dieser Anforderung fehlt der erforderliche Eingabetag "" in German.

First of all if you make request in a browser (99% sure) you have to look at the browser source HTML code (CTRL+U), there is a tag info will be shown that hidden in "pretty" browser view.

In my case I missed up eBay developer API AddItem method Item.PrimaryCategory.CategoryID tag that is not required in docs but required in real.
