It is maybe happening because the wasm instance is trying to import some undefined resources, especially that wasm-bindgen feature on rapier3d crate, or other dependencies that might happen to use a std unsupported feature for spacetimedb.
You see, even if spacetime-db modules work on top of a wasm runtime, it is extremely different from the one that is used for wasm-bindgen which targets wasm runtimes underneath Javascript runtimes (like the browser, Node.js, Deno, Bun, ect...).
First, remove the wasm-bindgen feature on rapier3d.
And if the problem still persists, another work around on this is to use the non-std features on your dependencies (that once_cell is probably a potential culprit for this scenario), which prevent them from using std unsupported features.
It is maybe happening because the wasm instance is trying to import some undefined resources, especially that
wasm-bindgenfeature onrapier3dcrate, or other dependencies that might happen to use astdunsupported feature for spacetimedb.You see, even if

I’ll give it a try and keep you posted
couldn't get it work, I believe main blocker is rapier and its dependencies. I'll put this initiative on hold for now. thanks
