React Table sort failure after upgrading dash 0.41.0 -> 0.42.0

Dash Python
1

I am in the process of upgrading an app to Dash 1.0.x.

I have a custom dash component that wraps react-table and applies extra styling and other things.

However, the table sort no longer works once I upgrade from Dash 0.41 -> 0.42 - the break is either in dash or in dash-renderer but am unable to find the root cause. Filtering and other elements of the table still work. No JS/dash errors are thrown.

A LOT changed in that version bump but appear mostly to be new files related to debug mode and callback visualizations.

Any help debugging this would be appreciated.

A simple version of this to debug with:

pip install dash==0.41.0 solvebio-dash-components==0.6.6

Run the simple app code below. Column sorting works just fine.

Then pip install dash==0.42.0

and now column sorting breaks.

import json
import dash
import solvebio_dash_components as sdc
import dash_html_components as html
from dash.dependencies import Input, Output

app = dash.Dash(__name__)

columns = [
    {
        'Header': 'Column A',
        'accessor': 'a',
    },
    {
        'Header': 'Column B',
        'accessor': 'b',
    }
]
app.layout = html.Div(
    children=[
        html.Div(
            sdc.DashReactTable(
                id='table-summary',
                data=json.dumps([
                    dict(a=1, b=3),
                    dict(a=2, b=4),
                    dict(a=10, b=100),
                ]),
                columns=json.dumps(columns),
            ),
        ),
        html.Div(
            html.H1("Sorted header", id="sorted-output")
        ),
        html.Div(
            html.H1("Sorted data", id="table-data")
        )

    ]
)


@app.callback(
    Output('table-data', 'children'),
    [Input('table-summary', 'data')])
def trigger_update(x):
    return x


@app.callback(
    Output('sorted-output', 'children'),
    [Input('table-summary', 'sorted')])
def trigger_update2(y):
    return y


if __name__ == '__main__':
    app.run_server(debug=True)
