Not really without some more information. Do you have the Heroku CLI installed? If not, install it, then type in this command into your terminal:

heroku logs --num 200 --app YOUR_APP_NAME

Obvious replace YOUR_APP_NAME with your app name, and sanitize anything you post here by removing any personally identifying information.

I did what you told me . The error i see in my terminal is about a api key. i have done everything correcly following the guide you made. maybe i missed something :/

I need to see the logs. Please open a support ticket on the GitHub project

This may be the result of the Heroku free quota running out too
