ReferenceError: self is not defined after migrating to sveltekit2

[noobmaster19]

Here's a shortened form of the error:

4:16:44 PM [vite] Error when evaluating SSR module 
...
ReferenceError: self is not defined

How did you encounter this? By upgrading sveltekit? Was it working with the previous version of sveltekit (or the lib)? Which line is it complaining about (can you click into it)? In general SSR should ignore the lib altogether

+1 getting the same [vite] Error when evaluating SSR module
ReferenceError: self is not defined

down grading from 0.9.34 to 0.9.33 helps but gives this warning

[vite-plugin-svelte] WARNING: The following packages have a svelte field in their package.json but no exports condition for svelte.

svelte-dnd-action@0.9.33

Please see https://github.com/sveltejs/vite-plugin-svelte/blob/main/docs/faq.md#missing-exports-condition for details.

@Rar9 yeah that's the warning 0.9.34 was supposed to fix. checking what this new error is about

[isaacHagoel]

I don't have time to get to the bottom of this now (hopefully tomorrow). The lib itself doesn't use "self" (it does use "window" quite a lot) so this error has to do with the code that rollup adds (the irony :)) as can be seen here. Version 0.9.33 has that too, see here so I am not sure why it doesn't trigger the same error. This wasn't a problem with Sveltekit 1 so very strange indeed.
This means that changes to the library code will not solve the issue. It has to be something in the rollup config or the exports config or god knows what.
I followed the advice on the link with 0.9.34 thinking it is a quick fix but looks like I was wrong.
Use 0.9.33 for now. It has all the latest feature.

I will try to make some time for this tomorrow. If anyone knows the solution please do let me know :)

[isaacHagoel]

okay, it was a silly mistake i made. please used 0.9.35

[Rar9]

your new updated works, iconify/svelte has the same issue ReferenceError ... what did u change?

[isaacHagoel]

I added this to package.json:

"exports": {
        ".": {
            "svelte": "./src/index.js"
        }
    },

Notice that it should point to src not dist, exactly like the top level "svelte" entry in package.json
