Troubleshooting a code component issue

In Framer, the error message “We detected a problem in one of your code components/overrides” signals an issue in your custom React code.

The most common cause is returning something other than a function inside a useEffect hook. For example:

useEffect(() => counterRef.current++, [someState])

This code returns a number to React due to the arrow function syntax, causing a crash. To fix it, wrap the function body in curly braces:

useEffect(() => { counterRef.current++ }, [someState])
