I'm getting error

GET http://localhost:3000/null 404 (Not Found)

in the console. I am using next js v12.1.6.

I am not going to the url localhost:3000/null. getting the error logged on the home page localhost:3000. Website is working perfectly otherwise. Looking at some other answers, which said it could be caused by a wrong img src, but this is not true in my case since I have only 1 image in my whole app and even after removing the img, the error still persisted.

My index.js file can be found here
My _app.js file can be found here
