Malformed syntax message – Need help to solve issue

Getting the following error trying to run a simple command using one of the sample calls provided in the Netsuite PHP SDK:

Fatal error: Uncaught SoapFault exception: [soapenv:Server.userException] The request could not be understood by the server due to malformed syntax. in /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php:296 Stack trace: #0 /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php(296): SoapClient->__soapCall(‘get’, Array, NULL, Array) #1 /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/PHPToolkit/NetSuiteService.php(157055): NSPHPClient->makeSoapCall(‘get’, Object(GetRequest)) #2 /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/outbound/add_order.php(8): NetSuiteService->get(Object(GetRequest)) #3 /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/index.php(36): include(‘/var/www/vhosts…’) #4 {main} thrown in /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php on line 296

I actually had everything working with version 2020_1, submitting sales order data, then I had to change my user password for my Netsuite account and  the process started failing.  So I updated my PHPToolKit to the latest version 2020_2, but I’m unable to continue due to the error.

Here is the information in my NSconfig file, minus my consumer key and token data:

define(“NS_ENDPOINT”, “2020_2”);

define(“NS_HOST”, “https://5478095.suitetalk.api.netsuite.com”);

define(“NS_ACCOUNT”, “5478095”);

define(“NS_CONSUMER_KEY”, “HIDDEN”);

define(“NS_CONSUMER_SECRET”, “HIDDEN”);

define(“NS_TOKEN”, “HIDDEN”);

define(“NS_TOKEN_SECRET”, “HIDDEN”);

I have verified that my consumer key, consumer secret, token and token secret are correct.   Also, my setup is fine because this was working fine before I had to change my password.   In version 2020_1 of the SDK, the config file required my username and password, but with this 2020_2 version of the SDK, the sample does not tell me to add this info.

Please, any clues would be appreciated on getting this resolved.
