Smappee [clientId not found]

[Ra7t0r]

Hello.
I hope that you are doing well.
I’m trying to make the Smappee.groovy Smartapp to work.
After enabling OATH, when I enter my credentitians on Smappee login screen on Smartapp configuration, I get an error:
“ClientId not found”
Any suggestions?
Is this project discontinued?
Thanks
