I am working on an object detection program and I am trying to build an app on top of the existing webcam app. I am using a macbook and running this on chrome. I have set up a http-server using npm.  
However, whenever I run the app (no changes to the code), I receive a 500 error code. It says that it is unable to get to my Roboflow API link.

How can I fix this? It was working just fine 3 days ago.

@Viba_Mohan @이범찬_디지털서비스팀 can you two try it again and click the URL that appears in the error?

This will give us more information on the underlying error that caused the `500`
