It does seem like there are some issues with ipycanvas in solara. I'm using ipycanvas 0.12.1, since higher versions don't seem compatible at all.
There's a hidden example on using ipycanvas here... Although I checked and it doesn't seem to be working as is, so I'll be taking a look at fixing things.
Interestingly, this code
import solara
import ipycanvas
from reacton import ipycanvas as c
from reacton import ipywidgets as w
count = solara.reactive(0)
@solara.component
def Page():
solara.Button(f"Draw {count.value}", on_click=lambda: count.set(count.value + 1))
def draw():
print(canvas_element)
canvas = solara.get_widget(canvas_element)
print(canvas)
with ipycanvas.hold_canvas(canvas):
canvas.fill_style = "#63934e"
canvas.fill_rect(10 * count.value, 10 * count.value, 10, 10)
solara.use_effect(draw, [count.value])
canvas_element = c.Canvas(
width=700,
height=500,
)
print(canvas_element)
Page = Page()
Pageruns fine if you execute it through a notebook cell (solara run app.ipynb), but not if you run it as a standalone app.

I want to develop an app that uses solara and ipycanvas, but it seems like ipycanvas isn't supported.
App code:
Then, I start the app:
And I get this error:
Is this expected? Are there any workarounds?
