Error on "Counter" contract example

Hi guys
I was just doing an intro to development on SWAY for a friend and we ran into the following error in the counter project

cargo test                                                                                                          (101) (*master+1) 14:58:33

Hey Alex, looks to me like what we solved here: Mismatched types - StorageKey<u64> - #14 by maurice

Let me know in case that doesn’t work for you :slight_smile:


Thanks ser
Will try :saluting_face:
