PR (https://github.com/plotly/dash-labs/pull/78) fixed most of the pathing issues (thank you so much!) as the homepage is showing up, but I still have one issue remaining. I have links that reference the various sub-pages on the top of my app and when I click on them they do not do anything (I just stay on the homepage) on Dash Enterprise (works when I run the multi-page app on my local machine).
I can workaround it for now by adding in the app name. So for example:
When I manually add in the name of the app ('capacity') to the address bar and press enter on the below link it does work:
https://appserver.host/capacity/regional
I believe this is an issue with how the page['path'] is served. I am serving up the page['path'] to a dcc.Link object as the href. I think that needs to have added on it the name of the app when hosted on Dash Enterprise.
ddk.Menu( children=[dcc.Link(page["name"], href=page["path"]) for page in dash.page_registry.values() if (not page["path"].startswith("/chapter")) and (page["path"].find("404") == -1)], )
I checked the server logs and the error I receive is below (similar to the one from before):
