Dear Community,

After migration from mysql to postgres, all existing incoming hooks doesn’t work. If I add a new one works, but existing I get an http 404 o 403 with this body:

```auto
{
    "id": "web.incoming_webhook.general.app_error",
    "message": "Failed to handle the payload of media type application/json for incoming webhook t7fybgmtwpng8dwgi3xdytzpzh.",
    "detailed_error": "",
    "request_id": "xjfob4wcz3bhmysusdu8ts47ic",
    "status_code": 403
}

```

Thanks for any help!

It’s a bit late, but for those finding this page via Google, it can be useful to know this error is most likely related to an incorrect `channel` in the request. Keep in mind that you can change the channel name in Mattermost, but this doesn’t automatically change the URL. The `channel` in the webhook request must match the channel’s URL.
