getProviders not working with getInitialProps and getStaticProps for me

[JakubKoralewski]

Here's the branch I'm trying to deploy. This is the page that's using the getStaticProps. I have verified it works with getServerSideProps.

Error with getStaticProps:

I tried setting the NEXTAUTH_URL env var from the heroku review app, but it didn't help. JakubKoralewski/lets-watch-it-together@4d9a136

It got fixed when using getServerSideProps. It's weird because it works with npm run dev, and it works with npm run build when NODE_ENV is not set to production. This is the weird part.

I'm familiar with https://nextjs.org/docs/basic-features/data-fetching#write-server-side-code-directly
"You should not fetch an API route from getStaticProps...", so if this is because of that then I can create a feature request instead.

I also conditionally enable next-pwa on NODE_ENV=production so I tried disabling next-pwa and reverted back to using getStaticProps with NODE_ENV=production npm run build and it's the same error as the previous getStaticProps one.
