SyntaxError: The requested module does not provide an export named 'prerendering'

[romelperez]

Describe the bug

Hello! After I updated SvelteKit to version 1.0.0-next.564, the app got a runtime error with the following message:

SyntaxError: The requested module '/node_modules/@sveltejs/kit/src/runtime/app/environment.js?v=f9512d5e' does not provide an export named 'prerendering'

I search for all my source code but there is no import for that dependency. I also reviewed the migration documentation in the PR which introduced that breaking change at #7762 but still the error was appearing.

When I searched for a possible import in the .svelte-kit folder output but I didn't find either the import to that dependency.

The app svelte.config.js looks like this:

import adapter from '@sveltejs/adapter-cloudflare';
import preprocess from 'svelte-preprocess';

const config = {
	preprocess: preprocess({
		postcss: true
	}),

	kit: {
		adapter: adapter(),
		alias: {
			$houdini: './$houdini'
		}
	}
};

export default config;

The @sveltejs/adapter-cloudflare was removed but still the error appeared.

Reproduction

I don't know what is adding the problem to the app, but in our source code, there is no import to that dependency.

Additional Information

Thank you!

Is there some third party package that maybe does use this? Your config hints that you use houdini - do they use that export?

[romelperez]

@dummdidumm, I am going to check it out.

Yes, it is Houdini package, a third-party package using that dependency. They just fixed it but haven't made a release.

Thank you for the quick response @dummdidumm !
