Error message
Error: Invalid hook call. Hooks can only be called inside of the body of a function component.
What broke
The error indicates that a React hook was called in a place where it is not allowed, such as outside of a functional component or inside a regular JavaScript function. Hooks must be used in the context of a functional component to manage state and lifecycle events.
Why it broke
This broke because React enforces a strict rule that hooks can only be called at the top level of a functional component. Calling them in nested functions, loops, or conditionals can lead to unpredictable behavior and is against the rules of hooks.
How to fix
To fix this error, ensure that all hook calls are made at the top level of a functional component. If you need to use hooks conditionally, refactor your code to call the hook unconditionally and use state or props to manage the conditional logic.
Code fix
function MyComponent() { const [state, setState] = useState(initialValue); /* other logic */ }Explained by ErrorOracle
Prevention tip
If you need to use hooks conditionally, refactor your code to call the hook unconditionally and use state or props to manage the conditional logic.
