Release with the issue: floor3d-card (aka Your Home Digital Twin) 1.5.3

Last working release (if known):

Browser and Operating System: Firefox 114.0.2 in Ubuntu 22.04.2

Description of problem: I get a generic error message when I point the Floor 3d card to my exported .obj/.mtl files. I exported my .obj/mtl files from SweetHome3D 7.1. I tried 2 different .sh3d files.

When I added a card with the default demo home.glb, the card loads and functions fine.

Javascript errors shown in the web inspector (if applicable):

Additional information: Floor3d Card is a fantastic idea! I hope I can get it to work for me!

Hello @mcmikemn, it is an unusual error, as a start, can you please share the YAML configuration ? Second, the home.json file is optional, try to load the model without the home.json file. If your model is very big there could be some limitations I have never tested, such as the size of the json file.

Thanks for the quick reply, @adizanni!

Here's the yaml for the Floor3d card:

When I exported from SweetHome3D, no .json file was included. Is that a problem?

What counts as "very big" regarding the size of the model?

[adizanni]

Please remove all references to the sample objects (object groups and entities), these are only valid when you use the sample model and are causing the card to fail because the objects do not exist anymore. Nevertheless the error message you receive is not the usual one for this problem and it may reveal other issues. Try and let me know

[mcmikemn]

That did the trick. Thanks. Why were demo object groups and entities included in the yaml? Am I running an old version of Floor3d Card?

[adizanni]

When you add a card from the gallery it comes with a sample model and sample objects attached to your entities. When you change the model you need to remove the references to the old model. I realized it is not very intuitive and I need to change the sample behavior.

Thanks for the explanation and the help!

This wasn't a bug, and @adizanni clarified what the fix was.
