Custom Error Page Not Working

Bug report

Describe the bug

I’ve been following the instructions here for some time: https://nextjs.org/docs#custom-error-handling

But it doesn’t seem that whether I deploy a site using @now/static-build or using @now/next, whenever I get a 404 on my site, the site gets redirected to the default now 404 page, not my custom page.

To Reproduce

I have a small example of a website that utilizes next and bulma and node-sass and @zeit/next-sass. Here’s the source code:

https://github.com/jvarness/next-with-bulma

For convenience, I have deployed this public project to zeit using both the next builder and the static-build builder.

https://next-with-bulma-72ahovqkn.now.sh/ <- next lambdas https://next-with-bulma-1lj0u8d2k.now.sh/ <- static

Might this have something to do with how next-sass alters the webpack config? I don’t think so but I’m unsure.

Expected behavior

When I go to the fake page on both, I should get the custom 404 page, but I just get the zeit one:

https://next-with-bulma-72ahovqkn.now.sh/fake https://next-with-bulma-1lj0u8d2k.now.sh/fake

Screenshots

I don’t have any screenshots for this.

System information

• OS: Windows
• Browser (if applies) Chrome
• Version of Next.js: 8.1.0

@Timer still doesn’t appear to be working for static. New URLs:

https://next-with-bulma-j9nerbg2e.now.sh/woop <- Lambdas https://next-with-bulma-7pamzks1f.now.sh/woop <- Static
