Missing local javascript files for _dash-component-suites

I’m trying to develop a test dash app with Dash 1.12.0 and I’m struggling with a couple of issues regarding access to (supposedly) missing javascript files. I know others have had this problem and I’ve tried most (if not all) suggestions but I’m stuck.

My simple app:

server = Flask(__name__)
app = dash.Dash(name = 'test', server=server)

app.layout = html.Div(children=[
        html.H1(children='Hello Dash')
])

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

This gives me the below errors in chrome. I know that after dash 1.0, things changed with respect to local js files being served by default instead of through a CDN. But where are these files locally? Are they supposed to be installed when dash (and its components) are installed? Any guidance would be appreciated!

I’ve been having the same issues. Seems there is very little guidance, I’ve tried setting the requests and routes path to ‘’ but still nothing.
