Setting setServerPassthroughCopyBehavior('passthrough') with Vite not working

[shoogstoel]

Operating system

Ubuntu

Eleventy

2.0.1

Describe the bug

When using setServerPassthroughCopyBehavior('passthrough'); in conjunction with '@11ty/eleventy-plugin-vite' results in the following error, when trying to run npx @11ty/eleventy --serve:

Init options have not yet been fetched in the setup callback. This probably means that `init()` has not yet been called.

Are there any known limitations when using Vite as middleware? Is there anything else I have to take care of when using passthrough?

Running into the same issue - worth noting that it doesn't matter whether server.middlewareMode in Vite settings is true or false.

It also appears that if passthrough behaviour is set to "copy", Vite doesn't seem to pick up changes to copied asset folders to trigger HMR

Yep, I just stumbled upon this error as well.

eleventyConfig.setServerPassthroughCopyBehavior("passthrough"); is a feature exclusive to the Eleventy Dev Server.

As you saying that the default behavior ("copy") isn’t working either?
