URDF example seems broken

[wuphilipp]

When trying the example on the README.md I get this error.

from vuer import Vuer, VuerSession
from vuer.schemas import DefaultScene, Urdf

app = Vuer()


@app.spawn(start=True)
async def main(session: VuerSession):
    app.set @ DefaultScene(
        Urdf("assets/urdf/robotiq.urdf"),
    )

    while True:
        await session.sleep(0.1)
