Custom _error.tsx that uses getInitialProps

[MatthieuVeillon]

Hi,

I have a troublesome issue. Not sure this is a bug per say and it might not even be related to your library - bear with me for that.

We use your library in conjunction with sentry ( following implementation from next-js repo example - this makes use of Error.getInitialProps in _error.tsx page)

It works well when deploying on Vercel / building locally but it fails invariantly when deploying on CircleCi. The culprit is next build where I get

Error occurred prerendering page "/404". Read more: https://err.sh/next.js/prerender-error Export encountered errors on following paths: /404 /404.html

This seems to come from a conflict between getInitialProps and getStaticProps where the 404 SSG conflicts with the getInitialProps from _error.tsx.

I thought it was related to the 404 page being SSG through your library therefore I tried to :

• remove the 404 page purely and simply from the app relying on Next default one - didn't change anything
• remove your webpack loader to add manually the fetching method on the pages, trying to avoid any getStaticProps on the 404 - didn't change anything neither.

As soon I SSR the 404 (which happens because of getInitialProps in _error.tsx) my build fails on CI.

I cannot really share the repo as its a private one with the NDA - will appreciate any help on this,

Thanks in advance
