Summary

When decoding hex values that have the valueType / valueContent of tuples like (Address,Bytes32), if the value that we are trying to decode is invalid like 0xdeadbeef, an empty array is returned.

It could be better to handle these cases by returning null maybe. This can improve the debugging experience.
