exception handling mechanism for using keyword parameters to orchestrate callbacks reported an error

[insistence]

Hi, there.
I encountered a bug while using the exception handling feature in version 2.18.
Dash related information is as follows

dash                          2.18.0
dash-core-components          2.0.0
dash-html-components          2.0.0
dash-table                    5.0.0

The test code is as follows

from dash import Dash, html, Input, Output, set_props


def global_callback_error_handler(err):
    set_props('output-global', {'children': f'global: {err}'})


app = Dash(on_error=global_callback_error_handler)

app.layout = [
    html.Button('start', id='start-local'),
    html.Button('start-global', id='start-global'),
    html.Div(id='output'),
    html.Div(id='output-global'),
    html.Div(id='error-message'),
]


def on_callback_error(err):
    set_props('error-message', {'children': f'message: {err}'})
    return dict(test=f'callback: {err}')


@app.callback(
    output=dict(test=Output('output', 'children')),
    inputs=dict(start=Input('start-local', 'n_clicks')),
    on_error=on_callback_error,
    prevent_initial_call=True,
)
def on_start(start):
    raise Exception('local error')


@app.callback(
    output=dict(test=Output('output-global', 'children')),
    inputs=dict(start=Input('start-global', 'n_clicks')),
    prevent_initial_call=True,
)
def on_start_global(start):
    raise Exception('global error')


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

The error message is as follows

dash._grouping.SchemaTypeValidationError: Schema: {'test': <Output `output-global.children`>}
Path: ()
Expected type: <class 'dict'>
Received value of type <class 'list'>:
    [<dash._callback.NoUpdate object at 0x00000215C014BF40>]

It seems to return a list containing NoUpdate by default.
