401 Unauthorized

So I'm using appwrite for the first time and am trying to insert something to my db, however, I keep getting this error in the console: AppwriteException: The current user is not authorized to perform the requested action.at Client.<anonymous>

I'm inserting the data without any user auth on the website - do I have to make an auth system? Or is there just something wrong with my api keys?

Also here's my code (I'm using SvelteKit):

<script>
  import { Client, Databases, ID } from "appwrite";
  import { client } from "$lib/appwrite";
  import {
    PUBLIC_APPWRITE_DB,
    PUBLIC_APPWRITE_COLLECTION,
  } from "$env/static/public";
  let val= "";

  const databases = new Databases(client);
  function submit() {
    const promise = databases.createDocument(
      PUBLIC_APPWRITE_DB,
      PUBLIC_APPWRITE_COLLECTION,
      ID.unique(),
      { url: "test data", hash: "test data" },
    );

    promise.then(
      function (response) {
        console.log(response);
      },
      function (error) {
        console.log(error);
      },
    );
  }
</script>
    <form
      on:submit={(e) => {
        e.preventDefault();
        submit();
      }}
    >
        <input
          bind:value={val}
          type="text"
        />
        <button type="submit">submit</button>
    </form>

Did you create a session using Account API before using the Databases APIs?

I think I did

Umm no, I dont see any login. See - https://appwrite.io/docs/products/auth/email-password

So I have to log the user in before they can use the db?

If the Databases permissions are set to Users.

But how can I set the db permission so anybody can access it?

Your Database > Your Collection > Settings > Permissions > Manage the Permissions.

However, granting read/write/update permissions to Any, Guest, All Users isn't a good security practice. What are you trying to do?

Well thanks for that, this is just kind of a test project, so just a few ppl will look at it and have the access to the db therefor, you don't have to be worried about spam/bots

In that case, you could still do this - Permissions > All Users > Select permissions.

Ofc. this would require the users to register & login. For registration, you can manually add the users via Auth dashboard & mark them as Verified.

And if I'd do guest, anyone would have access to it without auth?

There a few gotchas here, for better info. see this doc - https://appwrite.io/docs/advanced/platform/permissions#permission-roles

alright, thanks
