Hi, I am running OTRS 3.1.21 on a debian 7. I use RPC calls to contact my OTRS and retrieve my tickets. With my PHP I made a search ******************************************************** $client = new SoapClient(null, array('location' => "${url}/otrs/rpc.pl", 'uri' => "Core", 'trace' => 1, 'login' => 'XXXXXXXXXXX', 'password' => 'XXXXXXXXXXX', 'style' => SOAP_RPC, 'use' => SOAP_ENCODED, )); $data = $client->__soapCall("Dispatch", array($username, $password, "CustomerUserObject", "CustomerSearch", "Search", "*", )); ******************************************************** Sometimes (it is not regular) I have a PHP soap fault. ******************************************************** Can't use string ("Core") as a HASH ref while "strict refs" ******************************************************** and no information in logs. Has anybody meet this problem ? Regards,
