## Overview

If your OTTO project appears to exist in the backend but is missing from the Atlas Brain search bar or project list, and attempting to re-add it returns a **Request failed: 400** error, this is a known indexing issue. Because the project already exists in the system, the platform blocks duplicate additions — but the project also fails to surface correctly in Atlas Brain. This requires a manual fix from the Search Atlas team.



## What Causes This Issue

This issue occurs when an OTTO project becomes out of sync between the backend and the Atlas Brain search index. The project record exists in the database, so re-adding it triggers a 400 error (duplicate entry), but it is not registered in the index Atlas Brain uses to display and search projects. This prevents Atlas Brain from connecting to the project or delegating tasks to it correctly.



## How to Resolve It

Because this issue involves a backend index mismatch, it cannot be fixed through the platform interface alone. To get the issue resolved as quickly as possible, follow these steps:

1. **Confirm the project exists:** Verify that your OTTO project (for example, brittanyelise.com) is visible in your OTTO section and is listed as active. Make a note of the exact domain or project name.
2. **Do not attempt to re-add the project:** Trying to add the same project again will return a **Request failed: 400** error because the backend already has a record of it. Additional re-add attempts will not resolve the issue and may complicate the fix.
3. **Gather the following information** before contacting support — having these details ready will allow the team to locate and re-register your project in the Atlas Brain index as quickly as possible:

   - The exact domain or project name (for example, brittanyelise.com)
   - A screenshot or description of the 400 error you received when attempting to re-add the project
   - Your account email or workspace identifier
4. **Submit a support request** by opening the chat widget in your Search Atlas dashboard (click the chat icon in the bottom-right corner) or emailing the support team directly. Paste the information you gathered in the previous step into your message so the team can prioritize and action your request without needing a follow-up.
5. **What happens next:** Once the support team receives your details, they will manually re-register the project in the Atlas Brain index. This resolves the mismatch and makes the project appear correctly in Atlas Brain search and the project list. Most cases are resolved within one business day. If you do not hear back within 24 hours, reply to your original support thread to follow up.
