How would you make an API call and pass data to client with Sveltekit?

I've just begun learning Sveltekit. I'm following the tutorial for Auth.js for making a custom login page (https://authjs.dev/guides/pages/signin), which passes a mapping of the providers to some properties to use client-side. I have done this exact thing in Next.js, but I'm running into an issue with Svelte giving me the error: "Internal server error: Cannot import $env/dynamic/private into client-side code". However, I'm not importing any private variables into the client-side.

Here's my system environment:

  System:    OS: Windows 11 10.0.22631    CPU: (20) x64 13th Gen Intel(R) Core(TM) i5-13600K    Memory: 24.62 GB / 63.76 GB  Binaries:    Node: 20.11.1 - C:\Program Files\nodejs\node.EXE    npm: 10.8.1 - ~\AppData\Roaming\npm\npm.CMD  Browsers:    Edge: Chromium (125.0.2535.92)    Internet Explorer: 11.0.22621.3527  npmPackages:    @auth/sveltekit: ^1.2.0 => 1.2.0    svelte: ^4.2.18 => 4.2.18

Specifically, I could have a "test.ts" with

import { AUTH_SECRET } from "$env/static/private";export const testValue = 1;

And then under "/src/routes/+page.svelte", I have

<script lang="ts">import { testValue } from "./test";console.log(testValue);</script>

"testValue" is defined in a file that imports a private variable, but it does not contain the environment variable. But Svelte still throws the error. I've tried passing the value to +page.server.ts, putting it in a load function, nothing is working for me. If I delete the import from the page, then the error goes away.

So how do I get data from presumably any API that requires a private key and pass it client-side?
