Error: Unable to access the 'prefix' property due to it being undefined

I am facing a puzzling issue with my Next JS app not functioning properly on initial load on mobile for certain pages.

Here is the error message I am encountering:

TypeError: Cannot read property 'prefix' of undefined

I apologize if this seems like jargon, but it's all the information I have. I am using Fortawesome and came across this thread, although I believe I am correctly importing and utilizing the icons. The odd part is that when I attempt to navigate to a page link, it throws a severe error. However, upon refreshing the page, it functions normally again. What could be causing this behavior?

Do you have any suggestions on how to resolve this issue or perhaps improve my debugging process? Thank you

Answer №1

Recently, I discovered that my build is still making references to old fontawesome icons.

I decided to remove two unused icons from the code, only to realize they are still being referenced somewhere obscure (not in my actual code). As a result, these icons remain in the code without any real purpose, but causing an error to occur.

import {
  faList,
  faCogs,
  faArrowCircleRight,
  faArrowCircleLeft,
} from '@fortawesome/free-solid-svg-icons'
library.add(faList)
library.add(faCogs)
library.add(faArrowCircleRight)
library.add(faArrowCircleLeft)
