Came here to post this, I have the same issue. Is there a solution/workaround? Seems like ReactPy and Ipywidgets are not playing nice anymore.

Upgrading anywidget may fix this

[chedaniel]

Hi there, I tried the most recent anywidget 0.7.1 and downgraded to 0.7.0 - same result. However, converting any example to using "idom" does work.

for example:

from reactpy import component, html, run


@component
def Photo():
    return html.img(
        {
            "src": "https://picsum.photos/id/237/500/300",
            "style": {"width": "50%"},
            "alt": "Puppy",
        }
    )


Photo()

Fails with the Javascript error.

However --

import idom



@idom.component
def Photo():
    return idom.html.img(
        {
            "src": "https://picsum.photos/id/237/500/300",
            "style": {"width": "50%"},
            "alt": "Puppy",
        }
    )


Photo()

Works as expected.
