Hi,
we are currently using JupyterHub for our team. When I try to use ipywidgets in JupyterLab I get tis JavaScript error (https adress is cutted out)
The Code
import ipywidgets as widgets
slider = widgets.FloatSlider(description='$x$')
text = widgets.FloatText(disabled=True, description='$x^2$')
def compute(*ignore):
text.value = str(slider.value ** 2)
slider.observe(compute, 'value')
slider.value = 4
widgets.VBox([slider, text])
The error from the notebook:
[Open Browser Console for more detailed log - Double click to close this message]

I have already tried both versions from another solution ipywidgets==7.6.5 or ipywidgets==7.7.2
The individual environment for each user (from Zero to JupyterHub solution) starts with ipywidgets==8.0.2. The problem is that we may need another version <8, due to your problem with voila Nbconvert and voila no ipywidgets - General - Jupyter Community Forum
Cross-post jupyter notebook - Ipywidgets are not displayed with JavaScript error - Stack Overflow
