Description
Describe the bug
Hi everyone, not sure if this is the correct place to post this, I already posted on Stack Overflow without luck.
I'm trying to use the package @rollup/browser on my project to generate a dynamic bundle as described here
I know it might sound as if this is not a vite issue, however when running the code I get the following errors:

My first question is, what exactly is the http://localhost:5175/node_modules/.vite/deps/bindings_wasm_bg.wasm file? Do I need to add a specific plugin for this file to exist?
Then there are other problems with the MIME type, which I think I already have a workaround for, and the last error in the screenshot I think it's probably related to the missing file.
Any suggestions about this?
