Hi guys, regarding the truffle assignment - when i used the instance.deposit({value:1000)} - everything went smoothly, however I wanted to see what would happen if i created a transfer, so i did instance.createTransfer({value:500}, 0xe784A0aBE1DFAf65116b0eFA83dB4E59108E7524)
However this returned the following errorā¦ What seems to be the issue?
Uncaught:
