# Troubleshooting
Common issues when using the Agentforce Conversation Client.
---
### Component throws "requires agentId"
**Cause:** `agentId` was not passed.
**Solution:** Pass `agentId` directly as a flat prop:
```tsx
```
---
### Chat widget does not appear
**Cause:** Invalid `agentId` or inactive agent.
**Solution:**
1. Confirm the id is correct (18-char Salesforce id, starts with `0Xx`).
2. Ensure the agent is Active in **Setup → Agents**.
3. Verify the agent is deployed to the target channel.
---
### Authentication error on localhost
**Cause:** `localhost:` is not trusted for inline frames.
**Solution:**
1. Go to **Setup → Session Settings → Trusted Domains for Inline Frames**.
2. Add `localhost:` (example: `localhost:3000`).
3. Restart the dev server.
---
### Blank iframe / auth session issues
**Cause:** First-party Salesforce cookie restriction is enabled.
**Solution:**
1. Go to **Setup → Session Settings**.
2. Find **Require first party use of Salesforce cookies**.
3. Disable it.
4. Save and reload.
---
### Multiple chat widgets appear
**Cause:** Component rendered more than once.
**Solution:** Render one instance in app layout only.
