Bug: Can't run @cf-wasm/proton in OpenNext Cloudflare. But it works on next js and next-on-pages

[clmnin]

I added @cf-wasm/proton and tried running the example api route to resize an image using photon (A high-performance image processing library written in rust).

While it works in the next js environment and on next-on-pages, it does not work in opennext-cloudflare's workerd environment

Caution

Middleware is not supported in minimal mode. Please remove the NEXT_MINIMAL environment variable

Here are minimal reproducible example for OpenNext and next-on-pages
