  6. Hey man I have followed your same steps as you have shown in this video. But I encountered an error while doing the part where I have to push to heroku. The error says this : No default language could be detected for this app. HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically. Please try to figure out something for this. Thanks in advance 😀
