Hi @huachuman , where did you see the errors? Are they in the developer console, did you get a notification, or somewhere else? Can you also make sure you're on the latest obsidian plugin? To upgrade:

1. Open Community plugins tab in Obsidian settings
2. Click the Check for updates button
3. Click the Update button next to Khoj, if available

I'm not able to reproduce the error, so trying to understand how you might be encountering it.

Can you check in https://app.khoj.dev/settings > Files > Manage whether you have any data indexed?

[huachuman]

So that error I get in the Obsidian console.

I can confirm that I'm on the latest version of the plugin (updated 9 days ago)

The only things I see in the files on https://app.khoj.dev/settings is a single PDF I uploaded a while ago for testing. I don't see anything in my obsidian vault there. I have also confirmed that the API key matches the one I have in Obsidian.

Could it have something to do with this?

So I was looking into this issue again. But I still can't reproduce the CORS issue you are facing. It'd be great if you can share the following details to investigate/reproduce the CORS issue you are facing:

• Obsidian Version: What is the exact Obsidian version you are using?
• Network Details: Are/were you by any chance using proxies, VPNs or trying to access Khoj from a firewalled/restricted network (like a university or company network)?

Hey @debanjum @sabaimran,

I'm also getting CORS error on obsidian side. I'm using cloudflare for security. Everything else related to Khoj is working correctly but sync doesn't work at all.
