This method has a Struct return type and one Struct [in] parameter.
The struct consists of an integer value, a float value, string value, and a nested struct value.
One of the nested struct members will have a ref to a nonexistent id value. This should
result in a Sender fault with subcode "enc:MissingID".

varInt (please enter an integer value)
