NullPointerException occurred with UDF for Dynamic URL parameters

[Former Member]

I had a scenario SOAP -> PO 7.40 -> HTTP_AAE ，And Dynamic URL parameters。

My UDF：

UDF

DynamicConfiguration conf = (DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);   DynamicConfigurationKey URLParam_uid = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP_AAE", "URLParamOne");   DynamicConfigurationKey URLParam_pwd = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP_AAE", "URLParamTwo");   DynamicConfigurationKey URLParam_mobile = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP_AAE", "URLParamThree");   DynamicConfigurationKey URLParam_srcphone = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP_AAE", "URLParamFour");   DynamicConfigurationKey URLParam_msg = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP_AAE", "URLParamFive");   conf.put(URLParam_uid, uid );   conf.put(URLParam_pwd, pwd);   conf.put(URLParam_mobile, mobile);   conf.put(URLParam_srcphone, srcphone);   conf.put(URLParam_msg, msg); return uid;

when I tested it， NullPointerException occurred like this：

NullPointerException

Somebody could help me to solve this problem？

Thank you
