Go "Cannot unmarshal" error when trying drone exec with secret key

I run
MY_SECRET=mybigsecret drone exec

and go this error

2018/01/20 14:52:44 Cannot unmarshal 'map[SECRET:<nil>]' of type map[interface {}]interface {} into a string value

drone info works fine
drone version 0.8.1 mac os

That looks like a YAML unmarshal error, indicating your YAML file is invalid. Please be sure to include the exact steps and sample files to reproduce when posting to the forum. Thanks!

Hmmm… I’ve updated drone and cannot reproduce this issue any more, please close this issue
