Please note, it seems to be related to rights accessing your servers from different login/accounts. For example, with my account [email protected] I ALWAYS get the problem, no matter the model. With a model working for @Cattn (https://sketchfab.com/3d-models/lamborghini-huracan-gt3-squadra-corse-sdc-648132e9899844c69b89afb1f1585353):
On chrome: error "cannot fetch"
On FF: error "NetworkError when attempting to fetch resource"
and please note this renders the model UNUSABLE for me, I must delete all the instances (and not only the spawner) of the model to be able to publish, and when I reintroduce any instance of the model I get again the error.
macOS here
My way to ALWAYS reproduce the bug: new spoke scene from "empty", a Crater scene is created. Get a random model from sketchfab (tried dozens of them) and publish, ok. Get a spawner and publish, ok. Copy the model URL to the spawner and publish, kaboom.
Adding on, Windows here
Everything said there is same here, also we have found a way around the bug
That's the way I've found, (actually the way i usually place models never would of thought there would be much of a difference) still looking into it will add everything i can to help
I can confirm that if I get the model link WITHOUT PLACING IT and put the link in a spawner everything works also for me, as @Cattn describes. This also REPAIRS models rendered unusable by their usage in the spawner, please see last part of my previous comment.
I was not able to reproduce on MacOS 12.0/Chrome 96

What about using the method?
I have done some more research. The "cannot fetch" error on Chrome is relative to
which points here:
it seems that under some conditions a thumbnail of something cannot be generated and the method fails asynchronously, etc. But here we are in Spoke internals, so I gracefully shut my mouth.
Also please note, I have been able to NOT hit the problem by disabling/enabling cache from the developer tools, but not in a consistent way, so just take this as a sidenote.
