SvelteKit: Netlify TypeError (void 0) is not a function (500 Internal Error)

Site name: teaches.co.il

I deployed my website (as usual) and for some reason it builds and deploys okay (no error), but when I reach the website’s domain, all pages give “500 Internal Error”.

When I look in Netlify Logs (using the render.mjs provided by SvelteKit), I see this error message:

Oct 19, 03:24:32 AM: e975f4d6 ERROR  TypeError: (void 0) is not a function
    at render_response (file:///var/task/.netlify/functions-internal/render.mjs:84004:31)

I’m using the latest versions of sveltekit and netlify-build, here’s my package.json:

	},

}

I don’t think I’ve changed anything critical in my code. It used to work. now it doesn’t.

Any ideas?

Hi @elron

If the issue is with the render function from Svelte, it is probably best to file an issue on the relevant repository (they maintain the @sveltejs/adapter-netlify plugin.)

Actually I finally got it working when I did “clear cache and redeploy site” in Netlify.
I don’t know why it fixed that issue.

lol

Thanks for your help though
