[SOLVED] CORs problem even on localhost

My frontend is screaming even it's the frontend is localhost.

I have tried to put * in hostname but still not fixed. Both in development and production.

What could be leading to this?

Have you added your localhost address on Platforms in your console?

Localhost should be added as a platform by default, but you can try specifically adding it

I even tried adding there * for wildcard. I am now trying to see if project id is sent in the header requests.

Thanks to @Steven he pointed out something interesting about query formats. And I was able to resolve the issue.

Glad your issue is resolved now! Please mark this post as solved by adding "[Solved]" in front of your post's title.

[SOLVED] CORs problem even on localhost

do you know how/why this code was like this?

First of all I used AI to generate much of the code. Could it be prompting or the AI not prioritising the latest documentation?

Probably the latter

1. Did AI install the Appwrite SDK package too?
2. Can you share what the code was?
3. Are you using the Appwrite docs MCP server?
4. How are you giving AI context about Appwrite?

1. Yes AI installed the SDK

2. The code

  const result = await     databases.listDocuments(DATABASE_ID,COLLECTIONS.SUBSCRIPTIONS, [Query.equal("user_id", user.$id)]); //Notice value isn't an array
  if (result.documents.length > 0) {
    navigate({ to: "/dashboard" });
  }
} catch (e) {
  console.log("No subscription found");
}```

3. No, I didn't start with the Appwrite docs MCP server.
4. Oh yes, but it seems Claude usually has old knowledge about Appwrite.

Weird...did you have different Appwrite SDKs installed?

All I changed was treating value as an array and things started working.

SUBSCRIPTIONS, [Query.equal("user_id", [user.$id])]);
