Gives me an error on this

@duaa99 my first guess is that it might be your bytecode. Is your bytecode correct?

[fselmo]

Invalid opcode seems related to bytecode as mentioned in this issue, please reference similar answers that point this is not a library issue. If it is believed to be, please feel free to reopen or ask to reopen.
