Debugging server-side rendering issue on Vercel.

Issues
1

Hi, I’m trying to debug this issue: my website SSRs properly in development, but not in its Vercel deployment. This means the Vercel deployment doesn’t work with JS disabled. In production it returns a <div id="__next"> with only the CSS styles inside, but no actual HTML elements. Any pointers on how to debug?

It seems to happen only when using a preview: false Plasmic loader

I think preview false does not feed prefetched data to plasmic context, (if you are implementing it the same way as some examples on documentation where you have a ternary and pass undefined as the prop’s value) therefore I guess it does not render on server thus seeing what you see

I’d guess this is expected behavior cause you are relying on client’s at that point

Great so I think I may have messed up the Plasmic loaders between server and client

6

you could still pass the prefetch data evenin preview mode, BUT that will work only on build time

or might…
(i’m just thinking out loud)
