When using pocketbase with svelte, pocketbase returns a 'fetch failed' error unless an instance of pocketbase is running using ./pocketbase serve'

So I have a simple svelte app in which I want to perform CRUD operations using pocketbase. I have setup a collection "user" in pocketbase which has a table of fields name and age. I tried to perform a create operation using svelte actions which accepts a form data (containing the name and age) and creates a new user in the collection.

import PocketBase from 'pocketbase'import { SECRET_EMAIL, SECRET_PASS } from '$env/static/private'export const actions = {    create: async({request}) => {        const pb = new PocketBase("http://127.0.0.1:8090");        await pb.admins.authWithPassword(SECRET_EMAIL, SECRET_PASS);        const form = await request.formData();        const name = form.get("name");        const age = form.get("age");        const newRecord = {            name,            age,        }        const record = await pb.collection("users").create(newRecord);    }}

But whenever I ran the dev server and tried to submit the form it would return the following error:

But the issue is resolved and I am able to perform the create operation successfully when I start the pocketbase server manually using ./pocketbase serve in a new terminal.

My question is am I supposed to run an instance of pocketbase manually like this or am I doing something wrong? My assumption is that the line const pb = new Pocketbase("http://127.0.0.1:8090"); starts the pocketbase server without my doing so manually.

And if I am supposed to do this then could you please also tell me what other steps I should take when building the app to deploy it? Thanks a lot!
