Django-plotly-dash with dash 1.11.0 throws TypeError when trying to render app

Describe your context
I have been using Django-plotly-dash to create dashboard with Ploty/Dash/Bootstrap4 components. The app was working fine until I upgraded from dash 1.10.0 -> 1.11.0. In 1.11.0, I am getting a TypeError exception. Unfortunately, I can't figure out if the Django-plotly-dash plugin would need an update (due to some breaking change in Dash) or there is some bug in 1.11.0.

Another user has filed a ticket with django-plotly-dash experiencing the same, and I added some information there which describes the packages that were updated that is causing this issue. Please see https://github.com/GibbsConsulting/django-plotly-dash/issues/237

Describe the bug
Getting a TypeError exception. Please see https://github.com/GibbsConsulting/django-plotly-dash/issues/237

Exception Type: TypeError at /dashboard/
Exception Value: expected string or bytes-like object

Expected behavior

A nice dashboard should load 😃, just like it did with dash v1.10.0.

Screenshots

N/A.

Reproduce the dashboard request at /dashboard/ with Dash 1.11.0 and compare it with Dash 1.10.0. Read the linked django-plotly-dash issue 237 for the package versions and traceback details; done means the dashboard loads without the expected string or bytes-like object TypeError.
