Based on the snippet you provided, I'm pretty sure you are getting this error since you are returning your JSX wrapped in curly brackets:
return {
<nav className="navbar navbar-expand-lg navbar-light bg-light">
...
</nav>
}
If you wrap your JSX in round-brackets it should fix this issue:
return (
<nav className="navbar navbar-expand-lg navbar-light bg-light">
...
</nav>
)
