incept implant error "'list' object has no attribute 'length'"

[LuckyPi]

Having trouble using the implant module. I've tried on Kali 2.0 and built a fresh Debian 8.5 build and followed the installation guide. It's probably something I've overlooked but both OS's give me the error below when attempting to use the implant module. The unlock module works great!

Help is appreciated.
