FloorspaceJS does not load

[kousu]

Description

I have a model whose geometry I can view in 3D view and edit in FloorspaceJS, but if I make a copy or even just rename it I can still see the 3D view but no longer edit; FloorspaceJS simply fails to load.

Current Behavior

The loading bar above FloorspaceJS fills but then nothing happens.

Expected Behavior

I would like to be able to edit my geometry.

Steps to reproduce

This is my model: however, even just you downloading it here is renaming/moving it so I expect you won't be able to see a working good example: in.osm.txt.

1. Create a basic floor plan
2. Save it
3. Run the simulation and verify reports are output
4. Rename the .osm file
5. Reload it
6. Try to edit the floor plan again

The warning about the weather file is spurious: re-adding the weather file I used doesn't make FloorspaceJS suddenly work, so I'm not going to bother including it (and it's not mine to share either).

Possible Solution

Operating System affected

Ubuntu 24.04

Environment

• Platform (Operating system, version, architecture): Ubuntu 24.04 x86_64

I got OpenStudio from https://openstudiocoalition.org/app/#/app/releases. Specifically this one.

I am actually running inside a distrobox container inside Arch. I don't know if that has anything to do with the problem.

Version of OpenStudio

3.10.0+86d7e215a1
