[Qiao-Jin]

This issue is caused by lack of support of ByteString type by SETITEM opcode (currently only support VMArray, Map and Buffer)

Then we should support it😀.

[shargon]

why it requires a setItem if in this code is not needed?

@ProDog could you check if it was solved? in #360 it seems that it works
