According to the n8n documentation of one click deploy to heroku, I clicked the button, named the app and set the required fields. later I generated SSL using ACM and the status is green. but in the logs H10 is coming. I talked with the officials as well, they said there is no problem in heroku end, H10 comes because there is some problem with your app code. But I haven’t done anything by myself. So what is causing the Application error?
