Got it — let’s break this down clearly. --- ## 🔎 What the Error Means The console shows:
Uncaught Error: Minified React error #310; visit https://react.dev/errors/310 -
React error codes: In production builds, React minifies error messages to save bundle size. Instead of a descriptive message, you get a number (here, #310). - Error #310 specifically points to a misuse of React hooks — most often useMemo, useEffect, or similar — being called incorrectly. - The stack trace shows useMemo being invoked (Object.aH [as useMemo]), which suggests that React detected an invalid hook call. --- ## ⚠️ Likely Causes This error usually happens when: - Hooks are called outside of a valid React component (e.g., inside a regular function, conditional, or loop). - Multiple React versions are bundled together, causing mismatched hook contexts. - Improper rendering environment: e.g., calling hooks inside a message handler (MessagePort.w in your trace hints at a web worker or postMessage callback). - Minified production build hides the full explanation, so you only see the code number. --- ## 🛠️ How to Fix It 1. Switch to development mode - Run the app with NODE_ENV=development. - This will show the full descriptive error instead of just #310. 2. Check hook usage - Ensure useMemo (and other hooks) are only called: - At the top level of a React function component. - Not inside conditionals, loops, or nested functions. - Example of incorrect usage: js if (condition) { const memoized = useMemo(() => compute(), []); } ✅ Correct usage: js const memoized = useMemo(() => { if (condition) return compute(); return fallback; }, [condition]); 3. Verify React versions - Run npm ls react react-dom or yarn why react. - Make sure only one version of React is installed and used. 4. Check message handlers / workers - The stack trace ends at MessagePort.w, which suggests hooks might be invoked inside a postMessage callback. Hooks must only run during React’s render cycle, not inside arbitrary event handlers. --- ## ✅ Summary - The error is a minified React hook misuse error (#310). - It’s likely caused by calling useMemo (or another hook) outside a proper React component render. - Fix: Run in dev mode to see the full error, then refactor code so hooks are only used at the top level of React components, and ensure React versions are consistent. --- Would you like me to pull up the full React error #310 explanation from the official docs so you can see the exact wording?
