This is probably a beginner mistake. I have an app at crud-with-forms.vercel.app. I'm doing GraphQL queries and mutations using server on a separate file in my components, since the page.tsx is using client. Everything works locally. When I deploy only the queries will work correctly and the mutations keep returning 500. I only have one page route. But there's something going wrong when posting form data from that page. Anyone else run into this before?
