I am attempting to put Dash behind some Java middleware called (shinyproxy)[https://www.shinyproxy.io/] however since the requests are being handled by the middleware there are some Dash resources that fail to load. 404s occur on
_dash-layout
_dash-dependencies
I’ve asked about this on the shinyproxy forum this was the advice I received:
that means the href being used was “/_dash-layout” and not “_dash-layout”. Do you control the hrefs? If so, removing the slash may solve your issue.
I’ve been trying to remove the leading slash.
Attempt 1
server = flask.Flask(__name__)
app = dash.Dash(__name__, server=server, url_base_pathname='')
This breaks the app with the following error: ValueError: urls must start with a leading slash
Attempt 2
Taken from the responses on the question Deploy Dash on apache server I tried to remove prefixes
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': ''
})
But that was probably never going to work!
Do you have any advice on removing the slashes for the requests? Or alternative solutions?
