I've tried a lot of things for this, but got no fix.
Here's my code:
[see next message] (had to remove some code bc char limit)
(sb.player returns a promise btw)
if I go http://localhost:3000/seen?username=xyz, the error is

 âœ“ Compiled in 1608ms (487 modules)
 âš  Fast Refresh had to perform a full reload due to a runtime error.

and I have no idea what to do, does anyone know?

do you mean the code or add it to the library?

of the library?

i mean.. it's on npm
can't you just check yourself

also weirdly, it seems to resolve the promise but then it keeps rerendering it (i added a console.log to it in node modules)

1 sec i think i got smth

oh no i did not

'use client';
import { useSearchParams } from 'next/navigation';

        setPath(window.location.pathname)
    })
    const [user, setUser] = useState({} as any) 
    setLoading(true)
    if (username) {
        sb.player(username).then(_user => {
            console.log(_user)
            setLoading(false)
            setUser(_user)
        }).catch(e => {
            console.log(e)})
    }
    if (loading) return (

    )
    return (

                        name="username" 
                        placeholder="Username" 
required 
id="username" 
defaultValue={username ?? 'Noobcrew'}
                    />
<input type="submit" value="Search" id="searchsubmit"/>
</form>
}
<br />

</div>
}
        </main>
    )
}

don't mind the horrific indenting, character limit ðŸ˜…

i know, i was saying "oh yes that one [the browser one]"

i know

but the player function gets the uuid

i also don't know why it's rendering even though it shouldn't with no username specified

i fixed the rerendering issue

useEffect(() => {
        if (username !== null) {
            setLoading(true)
            sb.player(username).then(_user => {
                console.log(_user)
                setLoading(false)
                setUser(_user)
            }).catch(e => {
                console.log(e)
            })
        }
    }, [])
