Queries break when in production on Vercel; work on localhost

The query is called like this:

  const { data } = api.useQuery(["user.!getCount"], {
    refetchInterval: interval * 1000,
    onSuccess: () => ...
  }

  const { data } = api.useQuery(["user.!getCount"], {
    refetchInterval: interval * 1000,
    onSuccess: () => ...
  }

every query works on localhost, but once it's deployed to Vercel they all give this same error

hm true. and that does happen sometimes if it has an error. it returns the html from _document.tsx. i thought it was happening every time but when it's not having an error it only returns the json from trpc so i never looked into it

i don't think so, everything has been working before. just for whatever reason this recent push caused these problems

Oh okay so that makes sense. the html comes when there's an error because vercel puts up this 500 page

i found a commit where it all works, the one right after is what has things break. later today ill look at the difference

an interesting thing i found is that on the deployments i get this error, it seems like vercel is hitting a cache...

jaiOP•3y ago

maybe since it's returning a page idk yea i have no clue, nothing really changed from the commit that worked to the commit that broke it

not oss if i'm stuck on this though i could make some repo @oscartbeaumont after more debugging I found that the error was being caused by not setting up an env variable on vercel
