Description

You should design your system with error handling in mind. For example if the database cannot be accessed when you call GET /api/videos, then your backend endpoint should return a properly formatted error message with a HTTP 500 error code.

Acceptance criteria

Given a client calls the /api/videos endpoint, When the server cannot connect to the database , Then:

• [ ] The server should respond with a 500 status code
• [ ] The server should respond with a json object indicating the type of error

Here is an example JSON response:

{ "success": false, "error": "Could not connect to the database" }
