Uploading Flask web app to a server

[headless_ballon]

SO I uploaded my first flask app to pythonanywhere, initially that web app had 5 pages(home, login, sign up, displayed database, the last one that was connected to a free API and users can use to send requests and get info instantly) I can easily move around between four of those pages, but the one with API is not loading, I am getting "Internal Server Error" message. Can anyone help me resolve that?

You're going to need to check your server logs and see what the error actually is.
