paraglide:lang cookie ignored when reloading url with no lang in it

[SaintPepsi]

Hi!

I just implemented the language switcher in our application and I can see the cooking for paraglide:lang getting set.

When remove all paths from the url to refresh back to the index page, the paraglide:lang gets set back to our default language.

Am I missing something here?

We also build the application for Capacitor, which is known not to do that great with cookies.
Do I need to create a custom preference handling system to make sure the user gets served the correct page?

Have you configured prefixDefaultLanguage: "always"?
The cookie is only used if the language is ambiguous. By default the default-language lives on / so that's considered unambigous. Only if you configure it so that the default language is also located on /lang will the cookie be used

Awesome, it looks like prefixDefaultLanguage: "always" does what we want!
I should have probably tried that before posting an issue.

We're using adaptor static to generate the site for our application. But since adding that key we're getting the error Could not create a fallback page - failed with status 302 which i'm guessing is related to the initial redirect that happens to the correct language path?

Have you had this before?

[LorisSigrist]

Yeah, you'll probably need to edit the entries for prerendering in svelte.config.js. Just point it to /en.

Hey @LorisSigrist I tried that, but that didn't seem to do anything.
I didn't realise that the error is actually coming from wrangler:

process.env.VITE_ADAPTER capacitor

/Users/hogers/Documents/repos/EATView 2/node_modules/wrangler/wrangler-dist/cli.js:29747
            throw a;

Node.js v21.7.2

import adapterAuto from '@sveltejs/adapter-auto';
import cloudflareWorkersAdapter from '@sveltejs/adapter-cloudflare-workers';
import staticAdapter from '@sveltejs/adapter-static';

function getAdapter() {
	console.log('process.env.VITE_ADAPTER', process.env.VITE_ADAPTER);
	switch (process.env.VITE_ADAPTER) {
		case 'capacitor':
			return staticAdapter({
				strict: false,
				pages: 'build/capacitor',
				assets: 'build/capacitor',
				fallback: 'index.html',
			});

		case 'cloudflare-workers':
			return cloudflareWorkersAdapter();

		default:
			return adapterAuto();
	}
}

Do you have any suggestions on how I can debug this?

I was able to resolve this redirect warning with here: sveltejs/kit#9386 (comment)

by not adding the i18n.handle to the list of Handles when building
