Common Errors

WeirdLintError1 report

This "WeirdLintError" with React hooks often arises from outdated or conflicting ESLint configurations, especially involving `eslint-plugin-react-hooks`. Resolve it by updating `eslint`, `eslint-plugin-react-hooks`, and `@typescript-eslint/*` packages to their latest versions via npm or yarn; then, ensure your ESLint configuration correctly enables the recommended rules for React Hooks. A full reinstall can sometimes be required, making sure to delete `node_modules` and `package-lock.json` before running `npm install`.

WorkAroundLintError1 report

The "WorkAroundLintError" often arises when ESLint rules, especially those from `eslint-plugin-react-hooks` like `react-hooks/exhaustive-deps`, are overly strict and flag valid code. To fix this, carefully review the dependencies suggested by the error message; if they are truly unnecessary or inclusion breaks functionality, disable the rule for that specific line using an ESLint comment like `// eslint-disable-next-line react-hooks/exhaustive-deps`. Alternatively, consider refactoring your code to align with the intended usage of hooks.
