It does not error.

Opening this page leads to a blank page, with error in the console.

layout = [
 html.Button("Button", id={"component": "button.dot"}),

@callback(
 Output({"component": "button.dot"}, "children"),
 Input({"component": "button.dot"}, "n_clicks"),

def test(n):
 return "test"
app = Dash(__name__)
app.layout = layout
app.run()
