🔍 Overview
Some Search Atlas users encounter errors when setting up or using the Slack integration, including a message stating 'Gemini 3.5 Flash is no longer available.' This article explains why these errors occur and how to resolve them quickly.
⚠️ Common Slack Integration Errors
The most frequently reported issues with the Slack integration include:
- 'Gemini 3.5 Flash is no longer available' — the AI model previously used for this feature has been deprecated and replaced.
- Silent failures after approvals — the integration appears to complete setup but does not return a successful result or confirmation.
- Channels not appearing — connected Slack channels may not display as expected within the platform.
✅ Step-by-Step Resolution
- Refresh the integration: In the left sidebar, go to Coworker → Connectors, and locate Slack. Disconnect the existing connection if one is shown.
- Reconnect your Slack workspace: Click Connect Slack and follow the on-screen authorisation steps. Make sure you are logged into the correct Slack workspace before proceeding.
- Verify channel access: After reconnecting, confirm that your Search Atlas agent has been added to the relevant Slack channels inside Slack itself. The agent must be a member of a channel to send or receive messages there.
- Test the integration: Send a test message or trigger an action through the platform to confirm the connection is working. A successful result will be confirmed on screen.
- Clear your browser cache: If the integration still does not respond as expected, clear your browser cache and cookies, then reload the platform and repeat the steps above.
💡 Why Did the Gemini Error Happen?
The 'Gemini 3.5 Flash is no longer available' error appeared because an earlier version of the AI model powering certain Search Atlas features was deprecated. Our engineering team has resolved this by updating the platform to use a supported model version. No action is required on your part to fix the model itself — the update has already been applied. If you still see this error message, it is likely a cached page. Clearing your browser cache and reloading the platform should resolve it.
🏢 Note for GoHighLevel (GHL) Account Users
If you are using Search Atlas through a GoHighLevel (GHL) account and cannot see the Slack integration option in your Settings page, this is expected behaviour. The Slack integration is currently not available for GHL-connected accounts. This is a platform-level restriction and is not related to your subscription tier or permissions.
🛠️ Troubleshooting Checklist
- Ensure you have admin permissions in your Slack workspace — without these, the authorisation step may fail silently.
- Check that your browser is not blocking third-party pop-ups, as the Slack authorisation flow opens in a new window.
- If using a company Slack workspace, confirm that your organisation's Slack admin has approved third-party app connections.
- Make sure your Search Atlas account has an active plan that includes AI agent and integration features.
