ValueError: no types given, on startup

[kwinkunks]

Immediately after starting the app on a template-generated poly example, both on my local machine and on an Azure RGS node, I get the following non-fatal errors:

ERROR:webviz_app:Exception on /_dash-update-component [POST]

ValueError: no types given

To reproduce:

• ssh -X s034-rgs0002.s034.oc.equinor.com
• source /prog/komodo/2023.02.06-py38-rhel7/enable
• komodoenv --no-update --root /prog/komodo kenv
• source kenv/enable
• pip install py
• Check out ert, main branch
• cd tests/performance_tests
• python performance_utils.py # Returns a tmp location
• ert vis /tmp/<-tmp-location->/poly/poly.ert

Expected behavior
The app should start without warnings.

Desktop (please complete the following information):

• OS: Linux (local machine and on Azure)
• Browser: Firefox

When running this locally on my mac (and on my rhel8 workstation), storage folder does not seem to be generated.
So when starting webviz-ert;
