Hi, I just tried deploying to netlify and it worked for my project, can you try it and see if it also works for you? https://delicate-jelly-5935eb.netlify.app/

The issue in this case was there were 1000+ instance models on a layout. During the same tick all the file requests went out and the number of file requests exceeded the number allowed by the browser.
The fix was to change from instance model to non instance model (since all the instance models used the same model data.) In this was, only one model requests the file and the other instances wait for that file to be loaded and then use the data locally, without additional external requests.
