What is the best way of delivering static assets to the client for custom apps?

It’s working!

The solution was coded in the Dash code as follows:

# In order to work on shinyproxy
app.config.supress_callback_exceptions = True
app.config.update({
    # as the proxy server will remove the prefix
    'routes_pathname_prefix': ''

    # the front-end will prefix this string to the requests
    # that are made to the proxy server
    , 'requests_pathname_prefix': ''
})

Thanks @fmichielssen again for your help :slight_smile:
