[Bug]: Deploying an SSR powered Gatsby app via the Netlify CLI breaks SSR pages

[Andreas (AK)]

Summary

I’m having issues with Gatsby SSR when I manually deploy the artifact to Netlify.
It seems that Netlify is not generating the __ssr function when I deploy manually via the CLI.
Steps I’ve taken:

• Installing the @netlify/plugin-gatsby via the TOML
• Installing the gatsby-plugin-netlify
• Adding command and publish to the netlify.toml
• Running the cli in a workflow via deploy --prod

The deployment happens and I can visit the site, but all the SSR pages are not available and redirect to the 404 page.

With automatic deployments (Git Bridge) it worked, but I need to get it running via the CLI.

Do you have any ideas what I’m doing wrong?

I found a solution! 🎉

For anyone who has a similar problem and comes across this issue via Google. My main problem was that I built the app using gatsby build and not the netlfiy cli and the build command netlify build. After the modification, all the related functions (like __ssr) were generated. These were located in the .netlify folder. So when deploying the build now I had to deploy the public/ folder and also the functions under .netlify/functions and it worked!
