.glb 3d model assets request fails (404) in oxygen deployment

[GT-Devalopment]

Hello,

I have a Hydrogen 1 store which has 3D models used with model-viewer. I am not using the standard hydrogen component for the model as I have my own customisation. I am using the web component. everything worked well briefly on first deployment but then loading the model assets started to fail to a 404. I have my models as .glb files in the public directory of my app and are less than the maximum size allowed by Oxygen (around 20mb overall). other files in that directory load normally. everything works well on a local dev environment or a Vercel deployment. could this be an issue with Oxygen its self or am i missing something about adding those 3d Models?

thanks
