Receiving a Tuple from a Starlette API Response? Here’s How to Fix It!

When developing APIs using frameworks like Starlette, it's common to face unexpected problems, especially when dealing with JSON responses. One common issue that developers run into is receiving a tuple when they expect a JSON response. This guide will take you through the problem, explain the underlying issue, and guide you on how to resolve it effectively.

Understanding the Problem

In your Front End code, you are trying to make an API call to get some association data. However, instead of receiving a JSON response, the output shows that you have a type of <class 'tuple'>. Here's a brief look at the relevant code:
