Dash 1.3 is not worked is ShinyProxy

I have tried to run Dash dashboart on ShinyProxy/ I use https://github.com/openanalytics/shinyproxy-dash-demo - and it worked.
But I changed dash on new version and it broke.
It’s works:
RUN pip install dash==0.36.0 # The core dash backend
RUN pip install dash-renderer==0.17.0 # The dash front-end
RUN pip install dash-html-components==0.13.5 # HTML components
RUN pip install dash-core-components==0.43.0 # Supercharged components

It’s not works:
RUN pip install dash==1.3.0 # The core dash backend
RUN pip install dash-renderer==1.1.0 # The dash front-end
RUN pip install dash-html-components==1.0.1 # HTML components
RUN pip install dash-core-components==1.2.0 # Supercharged components

Message: Error loading layout

Hi,

Thanks for posting this, this gave me the clue to solve my issue which is the same as yours. I managed to get it back online by using these version:

dash==1.1.1
dash-bootstrap-components==0.7.1
dash-core-components==1.1.1
dash-html-components==1.0.0
dash-renderer==1.0.0
dash-table==4.1.0

Hopefully this issue will be fixed.
