Querying the avg of a decimal field and doing top 10, issue on the amount of decimals

500 internal server error on Heroku, while webapp runs locally
I successfully deployed a personal Django+React project built on Heroku but when I load the URL to my Heroku app I immediately get a 500 internal server error. From the console in Chrome it looks like this: Failed to load resource: the server responded with a status of 500 (Internal Server Error) and is caused by calling the endpoint /spotify/is-authenticated. This is called in a useEffect-hook (React) to check if the user is already logged in when a user enters the web page.
