window is not initialized issue

[jacobknighj12]

This issue was fixed with a simple window !== 'undefined' check in a couple places. as this project seems dead to the owner I forked and updated my own version feel free to use it if you have the same problem:
https://github.com/jacobknighj12/react-facebook-pixel
yarn upgrade react-facebook-pixel@https://github.com/jacobknighj12/react-facebook-pixel.git

While your solution looks good on first sight, when you look closer, I think it does the wrong thing – namely it injects the script if it's initialized (as evidenced by the if (initialized) wrapper).

So if anything, I think you'd need to adapt it to handle the check for window separately of initialization:

init(pixelId, advancedMatching = {}, options = defaultOptions) {
  if (typeof window === undefined) return

  initialized = !!window.fbq;
  // ...
}

I'm not sure if this fixes issues, but at least it should make code behave sensibly.
