> NOTE: version 0.10.0 of `pg_net` is out. You should consider updating your database in the [General Settings](/dashboard/project/_/settings/general) if you are on a prior version. If you do not know your version, you can check the [Extensions Dashboard](/dashboard/project/_/database/extensions).
|
|
|
|
**Debugging Steps**
|
|
|
|
**1. Test if webhooks are active:**
|
|
Webhooks are run in a Postgres background worker. The first debugging step is to see if the worker is active. Run the following SQL code:
|
|
|
|
```sql
|
|
select pid from pg_stat_activity where backend_type ilike '%pg_net%';
|
|
```
|
|
|
|
If it does not return an integer, then the worker has failed and needs to be restarted. If you are running PG_NET 0.8 or later, you can restart the background worker by executing the following function:
|
|
|
|
```sql
|
|
select net.worker_restart();
|
|
```
|
|
|
|
Otherwise, it is necessary to fast reboot your instance in the [Dashboard's Settings](/dashboard/project/_/settings/general).
|
|
|
|
**2. Remove any triggers on net tables:**
|
|
|
|
Using `pg_net` in triggers on most tables is fine; however, do not add triggers to the `net._http_response` or `net.http_request_queue` tables.
|
|
|
|
The `net` tables are special and if triggers on them fail or call a pg_net function (`http_get`, `http_post`, `http_delete`), it can lead to an infinite loop. This warning is irrelevant to most projects, but it's worth specifying in case.
|
|
|
|
**3. Check for timeout errors**
|
|
|
|
> **NOTE**: The timeout issue has been patched in `pg_net` v0.11. It is available in Postgres 15.6.1.135 and above. You can upgrade your version of Postgres in the [General Settings](/dashboard/project/_/settings/general).
|
|
|
|
Go to your [Table Editor](/dashboard/project/_/editor/) and navigate to the net schema. It will contain two tables:
|
|
|
|
- `_http_response`
|
|
- `http_request_queue`
|
|
|
|
The `_http_response` table saves all the response messages from the past 6 hours. If every column contains NULL values, except for the `id`, `error_msg`, and `created` columns, then you are experiencing [a timeout bug](https://github.com/supabase/pg_net/issues/86).
|
|
|
|
By default, webhooks will execute the next 200 available queued requests. If the requests are too intense, it may result in a mass timeout. In the [Webhook Dashboard](/dashboard/project/_/database/hooks), you should increase your webhook's timeout to minimize this issue.
|
|
|
|
**4. Inspect endpoints**
|
|
The below code makes a request to the Postman Echo API through PG_NET
|
|
|
|
```sql
|
|
select
|
|
net.http_post(
|
|
url := 'https://postman-echo.com/post',
|
|
body := '{"key1": "value", "key2": 5}'::jsonb
|
|
) as request_id;
|
|
```
|
|
|
|
Postman will then respond with the same payload. This is a test to confirm that requests are being properly formatted and going through.
|
|
|
|
You can then view the request in the `net._http_response table` in the [Table Editor](/dashboard/project/_/editor) or with the following SQL:
|
|
|
|
```sql
|
|
select
|
|
*
|
|
from net._http_response
|
|
where id = <request_id>
|
|
```
|
|
|
|
You should also inspect all the failed responses from the past 6 hours to see if their are any insightful messages:
|
|
|
|
```sql
|
|
select
|
|
*
|
|
from net._http_response
|
|
where "status_code" >= 400 or "error_msg" is not null
|
|
order by created desc;
|
|
```
|
|
|
|
Status codes from a server are described in [Mozilla's web docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status)
|
|
|
|
**5. Create logs**
|
|
|
|
If none of the above suggestions uncovered the cause of the error, for debugging purposes, it may be useful to write a custom webhook that can create logs in the [Dashboard's Postgres Logs](/dashboard/project/_/logs/postgres-logs). The process is outlined in the [PG_NET](/docs/guides/database/extensions/pg_net#debugging-requests) documentation.
|
|
|
|
**Conclusion:**
|
|
|
|
If your issue still persists, document it as an issue in the [PG_NET GitHub Repo](https://github.com/supabase/pg_net/issues). You are also welcome to contact Supabase Support from your project's [Dashboard](/dashboard/project/_/) for more guidance.
