dts script task has encountered exception in user code: exception has been thrown target of invocation

with following stacktrace:

at system.runtimemethodhandle.invokemethod(object target, object[] arguments, signature sig, boolean constructor) @ system.reflection.runtimemethodinfo.unsafeinvokeinternal(object obj, object[] parameters, object[] arguments) @ system.reflection.runtimemethodinfo.invoke(object obj, bindingflags invokeattr, binder binder, object[] parameters, cultureinfo culture) @ system.runtimetype.invokemember(string name, bindingflags bindingflags, binder binder, object target, object[] providedargs, parametermodifier[] modifiers, cultureinfo culture, string[] namedparams) @ microsoft.sqlserver.dts.tasks.scripttask.vstataskscriptingengine.executescript()
