Example project does not work in 4.0.6 when using simwrapper run config.yaml: cannot access local variable 'e' where it is not associated with a value

[b-a0]

When I try to run the example project using simwrapper 4.0.6 navigating to the dashboards (under /data/dashboards/) leads to the error:

cannot access local variable 'e' where it is not associated with a value

In the UI this results in an error at the bottom of the screen:

Error parsing: dashboards/4-charts-and-maps/dashboard-2-maps.yaml

Steps to reproduce

1. Create the following folder structure:

   |- data/
   |---- berlin/
   |---- dashboards/
   |---- <etc... all contents of the example project>
   |- config.yaml
   

2. Edit config.yaml such that it looks like this:

   storage:
     simwrapper:
       path: './data'
       description: 'Local data from this server'
   
   tagline: 'Config file for issue'
   readme: |
     Dummy text for issue
     ====================

3. In the top-folder (where config.yaml resides) run: uvx simwrapper==4.0.6 run config.yaml --debug
4. Open http://localhost:4999, navigate to simwrapper -> dashboards -> 4-charts-and-maps
   • Or go there directly: http://localhost:4999/simwrapper/dashboards/4-charts-and-maps/

Expected outcome

The dashboard is shown, with graphs and an option in the sidebar to go to a page with maps.

Actual outcome

The folder contents are shown in the Simwrapper "file lister" and an error is shown at the bottom:

In the commandline that is running simwrapper I see:

DEBUG:simwrapper:DIR simwrapper /
DEBUG:simwrapper:DIR simwrapper /dashboards/
DEBUG:simwrapper:GET simwrapper dashboards/4-charts-and-maps/dashboard-1-charts.yaml
cannot access local variable 'e' where it is not associated with a value
DEBUG:simwrapper:GET simwrapper dashboards/4-charts-and-maps/dashboard-2-maps.yaml
cannot access local variable 'e' where it is not associated with a value

Workaround

If I keep everything the same, but in step 3 run: uvx simwrapper==4.0.5 run config.yaml --debug (4.0.5 instead of 4.0.6) I get the expected outcome.
