Error Creating Encrypt key with Heroku

Hello There

I have had some issues configuring travis encrypt.
When I run:
travis encrypt $(heroku authorizations:create) --add deploy.api_key
Travis shows me this error:

The name of the repo before was poc-incidents_frontend, I changed the name to incidents-frontend, but still showing the same error.
Travis version:
1.8.9

The .git/config:
[travis]
slug = Danachury/incidents-backend

Did I forget some configuration?
