Weired error when deploying to Vercel

[waylio]

Hey Andy,

I'm getting this error when deploying to Vercel. Its works perfectly on localhost and also works on another project in production. I'm not sure what is the problem here.

Thanks in advance.

Hey thanks for the report 👋

I know there were users successfully using this with SSR (#317) - any chance you can provide a reproduction so I can look into this?
