I successfully deployed a .Net Core 3.1 app example with docker to Heroku. But when i try to run it, it shows me the following message:
Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail
When i run this heroku logs --tail command i recieve this Error: missing required flag: -a, --app APP app to run command against. Please, how can i see a further error description ?
