According to Configuration Extension | Drone the value under the uid key in the repo dict should be an integer, but in my testing it appears to be a string instead which breaks a configuration extension I am trying to develop in Go. I can use a string instead as a quick fix, but it may be something worth fixing, either in the docs or in the code.
uid is definitely a string value  which means the documentation is inaccurate and needs to be updated accordingly.
I see it’s been updated now. Cheers!
