- Rewrite the four longest guides (RAG background jobs, webhook debug, bot setup, onboarding) at roughly half the length: drop historical bug-fix notes, duplicated command blocks, ASCII mega-diagrams and filler sections, keep everything operationally useful. - Remove provider-specific recommendations; examples are now neutral OpenAI-compatible endpoints. - Fix stale content: dead doc links in docs/README.md, old repo issue URLs, catalogue tools (now provided via the tool-provider extension point, not built-in), supported NC versions, clone URL in quick start. - Slim DEVELOPMENT.md down to build/test/migration essentials. docs/ shrinks from 2850 to 1278 lines with no loss of setup, debugging or architecture coverage.

# Webhook Debugging
|
|
|
|
What to check when a bot doesn't respond in Talk.
|
|
|
|
## Diagnostic Steps
|
|
|
|
**1. Bot activated in the room?** Open the conversation settings (⚙️) and confirm "Talk AI" is active in the bots list.
|
|
|
|
**2. Webhook registered?**
|
|
|
|
```bash
|
|
sudo -u www-data php occ talk:bot:list
|
|
```
|
|
|
|
You should see the `Talk AI` bot with `state = 1` and features `webhook, response`. A growing `error_count` means Talk can't deliver webhooks — usually a wrong URL (see below).
|
|
|
|
**3. Watch the log while mentioning the bot:**
|
|
|
|
```bash
|
|
tail -f /path/to/nextcloud/data/nextcloud.log | grep -i educai
|
|
```
|
|
|
|
A successful interaction logs this sequence:
|
|
|
|
```
|
|
========== Talk AI Webhook Received ==========
|
|
Extracted webhook data (message: "@mybot hello", room_token: "xxx")
|
|
Bot detected (bot_id: 1, mention_name: @mybot)
|
|
Calling LLM API
|
|
Got LLM response
|
|
Successfully sent reply to Talk
|
|
========== Webhook Processing Complete ==========
|
|
```
|
|
|
|
Where the sequence stops tells you what failed:
|
|
|
|
| Log stops at | Likely cause |
|
|
|---|---|
|
|
| Nothing at all | Bot not activated in the room, wrong webhook URL, or network issue |
|
|
| "Invalid webhook signature" | Webhook secret in settings ≠ secret used in `talk:bot:install` |
|
|
| "No bot mention found" | Typo or case mismatch in the @mention name, or the bot doesn't exist |
|
|
| "Failed to get LLM response" | Wrong endpoint/key/model, or no network route to the provider |
|
|
| "Failed to send reply to Talk" | Talk API issue or invalid room token |
|
|
|
|
## Common Issues
|
|
|
|
### 405 Method Not Allowed — webhook URL missing `/index.php`
|
|
|
|
The most common problem. The webhook URL **must include `/index.php`** on installations that route apps through it:
|
|
|
|
- ❌ `https://cloud.example.com/apps/educai/webhook/talk`
|
|
- ✅ `https://cloud.example.com/index.php/apps/educai/webhook/talk`
|
|
|
|
Fix by re-registering:
|
|
|
|
```bash
|
|
sudo -u www-data php occ talk:bot:uninstall "Talk AI"
|
|
sudo -u www-data php occ talk:bot:install \
|
|
-f webhook,response \
|
|
"Talk AI" \
|
|
"your-webhook-secret" \
|
|
"https://cloud.example.com/index.php/apps/educai/webhook/talk"
|
|
```
|
|
|
|
### Signature verification fails
|
|
|
|
The secret saved in Talk AI settings must exactly match the one passed to `talk:bot:install`.
|
|
|
|
1. Generate a secret: `openssl rand -hex 32`
|
|
2. Save it in the Talk AI admin settings.
|
|
3. Re-register the bot with the same secret (commands above).
|
|
|
|
For local testing only, an empty webhook secret skips verification.
|
|
|
|
### "Sorry, I'm having trouble connecting…"
|
|
|
|
The webhook works; the LLM call fails. Verify endpoint, key, and model name, and test directly:
|
|
|
|
```bash
|
|
curl https://your-api-endpoint/v1/chat/completions \
|
|
-H "Authorization: Bearer YOUR_API_KEY" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"model":"your-model","messages":[{"role":"user","content":"test"}]}'
|
|
```
|
|
|
|
## Payload Reference
|
|
|
|
Talk delivers messages as signed POST requests. Useful when testing by hand:
|
|
|
|
```
|
|
Message text: $payload['object']['content'] → JSON-decode, read the 'message' key
|
|
Room token: $payload['target']['id']
|
|
User ID: $payload['actor']['id']
|
|
Message ID: $payload['object']['id'] → string in the payload, used as int
|
|
```
|
|
|
|
Replies back to Talk are signed with:
|
|
|
|
```php
|
|
'X-Nextcloud-Talk-Bot-Random' => $random,
|
|
'X-Nextcloud-Talk-Bot-Signature' => hash_hmac('sha256', $random . $message, $secret)
|
|
```
|
|
|
|
Manual webhook test:
|
|
|
|
```bash
|
|
cat > /tmp/test-webhook.json <<'EOF'
|
|
{
|
|
"type": "Create",
|
|
"actor": { "type": "user", "id": "admin", "name": "Admin" },
|
|
"object": { "type": "message", "id": 1,
|
|
"content": "{\"message\":\"@mybot test\",\"parameters\":[]}" },
|
|
"target": { "type": "chat", "id": "test-room-token", "name": "Test Room" }
|
|
}
|
|
EOF
|
|
|
|
curl -X POST http://localhost/index.php/apps/educai/webhook/talk \
|
|
-H "Content-Type: application/json" \
|
|
-d @/tmp/test-webhook.json \
|
|
-w "\nHTTP: %{http_code}\n"
|
|
```
|
|
|
|
(Without valid signature headers this exercises routing and parsing, not the full flow.)
|
|
|
|
## Advanced
|
|
|
|
```bash
|
|
# raise log level
|
|
sudo -u www-data php occ log:manage --level debug
|
|
|
|
# check delivery failures
|
|
sudo -u www-data php occ talk:bot:list # error_count column
|
|
```
|
|
|
|
If it still doesn't work, open an issue with the log excerpt (from "Webhook Received" to the failure), your Nextcloud version, and whether the LLM endpoint works when called directly.
