Svelte frontend deploy failed while building code

1

I am making frontend in sveltejs (not sveltekit integration). I am trying to deploy the project in render but deploy is failing at the time of build.
I tried to follow the way mentioned here: Deploy a Svelte Static Site | Render
my configuration is:
/*
“name”: “bdehrfrontend”,
“private”: true,
“version”: “0.0.0”,
“type”: “module”,
“scripts”: {
“dev”: “vite”,
“build”: “vite build”,
“preview”: “vite preview”,
“check”: “svelte-check --tsconfig ./tsconfig.json”
},
/
Error message is:
/

Hi,

The error from the shared deploy logs is:

ReferenceError: performance is not defined

Doing a search for that error + “Svelte” returns several results, one of which is here: Fixing "performance is not defined" Issue with Svelte/SvelteKit :: Casey Primozic's Notes

That seems to suggest the Node version could be an issue here.

You’ve not shared all the deploy logs so I can’t see what Node version you’re using, however, that is shown near the top of the deploys logs, e.g.:

==> Using Node version 14.17.0 (default)
==> Docs on specifying a Node version: https://render.com/docs/node-version

Maybe try setting the Node version to the same one you tested/developed on as a first step.

Alan
